ALICE: Physics Performance Report, Volume II

Abstract: ALICE is a general-purpose heavy-ion experiment designed to study the physics of strongly interacting matter and the quark–gluon plasma in nucleus–nucleus collisions at the LHC. It currently involves more than 900 physicists and senior engineers, from both the nuclear and high-energy physics sectors, from over 90 institutions in about 30 countries.The ALICE detector is designed to cope with the highest particle multiplicities above those anticipated for Pb–Pb collisions (dNch/dy up to 8000) and it will be operational at the start-up of the LHC. In addition to heavy systems, the ALICE Collaboration will study collisions of lower-mass ions, which are a means of varying the energy density, and protons (both pp and pA), which primarily provide reference data for the nucleus–nucleus collisions. In addition, the pp data will allow for a number of genuine pp physics studies.The detailed design of the different detector systems has been laid down in a number of Technical Design Reports issued between mid-1998 and the end of 2004. The experiment is currently under construction and will be ready for data taking with both proton and heavy-ion beams at the start-up of the LHC.Since the comprehensive information on detector and physics performance was last published in the ALICE Technical Proposal in 1996, the detector, as well as simulation, reconstruction and analysis software have undergone significant development. The Physics Performance Report (PPR) provides an updated and comprehensive summary of the performance of the various ALICE subsystems, including updates to the Technical Design Reports, as appropriate.The PPR is divided into two volumes. Volume I, published in 2004 (CERN/LHCC 2003-049, ALICE Collaboration 2004 J. Phys. G: Nucl. Part. Phys. 30 1517–1763), contains in four chapters a short theoretical overview and an extensive reference list concerning the physics topics of interest to ALICE, the experimental conditions at the LHC, a short summary and update of the subsystem designs, and a description of the offline framework and Monte Carlo event generators.The present volume, Volume II, contains the majority of the information relevant to the physics performance in proton–proton, proton–nucleus, and nucleus–nucleus collisions. Following an introductory overview, Chapter 5 describes the combined detector performance and the event reconstruction procedures, based on detailed simulations of the individual subsystems. Chapter 6 describes the analysis and physics reach for a representative sample of physics observables, from global event characteristics to hard processes.

Search for neutral MSSM Higgs bosons at LEP

Abstract: The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric standard model (MSSM). The data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and with a possible Higgs boson signal. The combined LEP data show no significant excess of events which would indicate the production of Higgs bosons. The search results are used to set upper bounds on the cross-sections of various Higgs-like event topologies. The results are interpreted within the MSSM in a number of “benchmark” models, including CP-conserving and CP-violating scenarios. These interpretations lead in all cases to large exclusions in the MSSM parameter space. Absolute limits are set on the parameter cosβ and, in some scenarios, on the masses of neutral Higgs bosons.

International Union of Pharmacology. LXV. The Pharmacology and Classification of the Nuclear Receptor Superfamily: Glucocorticoid, Mineralocorticoid, Progesterone, and Androgen Receptors

Abstract: The glucocorticoid receptor (GR[1][1]), mineralocorticoid receptor (MR), progesterone receptor (PR), and androgen receptor (AR) are classic members of the nuclear receptor superfamily, composing subfamily 3C. Members of this subfamily are among those receptors that were cloned the earliest, with the

Nuclear modification of electron spectra and implications for heavy quark energy loss in Au+Au collisions at sNN=200GeV

Abstract: The PHENIX experiment has measured midrapidity ([FORMULA: SEE TEXT]) transverse momentum spectra ([FORMULA: SEE TEXT]) of electrons as a function of centrality in Au+Au collisions at [FORMULA: SEE TEXT]. Contributions from photon conversions and from light hadron decays, mainly Dalitz decays of pi0 and eta mesons, were removed. The resulting nonphotonic electron spectra are primarily due to the semileptonic decays of hadrons carrying heavy quarks. Nuclear modification factors were determined by comparison to nonphotonic electrons in p+p collisions. A significant suppression of electrons at high pT is observed in central Au+Au collisions, indicating substantial energy loss of heavy quarks.

Measurement of high-pT single electrons from heavy-flavor decays in p+p collisions at s=200GeV

Abstract: The momentum distribution of electrons from decays of heavy flavor (charm and bottom) for midrapidity |y|< 0.35 in p+p collisions at s=200 GeV has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over the transverse momentum range 0.3 < p(T)< 9 GeV/c. Two independent methods have been used to determine the heavy-flavor yields, and the results are in good agreement with each other. A fixed-order-plus-next-to-leading-log perturbative QCD calculation agrees with the data within the theoretical and experimental uncertainties, with the data/theory ratio of 1.71 +/- 0.02(stat)+/- 0.18(sys) for 0.3 < p(T)< 9 GeV/c. The total charm production cross section at this energy has also been deduced to be sigma(cc)=567 +/- 57(stat)+/- 193(sys) mu b.

Enteral (oral or tube administration) nutritional support and eicosapentaenoic acid in patients with cancer: a systematic review.

Abstract: The aim of this systematic review was to determine the efficacy and potential benefits of enteral nutritional support [oral nutritional supplements (ONS) or enteral tube feeding (ETF)], and eicosapentaenoic acid (EPA, free acid, ethyl esters or fish oil; provided as capsules or enriched ONS or ETF) in patients with cancer Clinical studies were identified using electronic databases, and studies were selected according to predetermined criteria For each treatment modality (chemo/radiotherapy, surgery, and palliative care), the comparisons of interest were nutritional support vs routine care (no nutritional support), EPA supplement (capsule or enriched ONS or ETF) vs routine care (no supplement or standard supplement), ETF vs parenteral nutrition (PN) The reviewed outcomes were dietary intake, anthropometry, clinical (mortality, length of hospital stay, complications, and quality of life) and haematological/biochemical (white blood cell count, serum transferrin and albumin, CD3-positive lymphocytes, and inflammatory markers) Meta-analyses were performed where possible In patients undergoing radiotherapy, meta-analysis showed that ONS significantly increase dietary intake (381 kcal/day, 95% CI 193 to 569 in 3 RCTs) compared to routine care In patients undergoing surgery, meta-analyses showed that ETF results in a significantly shorter length of hospital stay (172 fewer days, 95% CI 090 to 254 in 8 RCTs), lower incidence of any complications (OR 062, 95% CI 050 to 077 in 4 RCTs) and infectious complications (OR 067, 95% CI 055 to 082 in 11 RCTs) and lower sepsis scores (221 points, 95% CI 149 to 292 in 2 RCTs), but no difference in mortality (OR 072, 95% CI 040 to 129 in 7 RCTs) compared to PN There was also no difference in mortality between ONS or ETF vs routine care in patients undergoing chemotherapy/radiotherapy (OR 100, 95% CI 062-161 in 4 RCTs) or surgery (OR 244, 95% CI 075 to 795 in 4 RCTs) Individual studies of EPA supplementation as capsules showed improvements in survival, complications and inflammatory markers in patients undergoing bone marrow transplant (BMT) In palliative care patients receiving EPA-enriched ONS or capsules, there were inconsistent positive effects on survival and quality of life In those undergoing surgery, EPA-enriched ETF had no effect Further research is required to elucidate the clinical efficacy of enteral nutrition support, including the potential benefits of EPA supplementation, in patients with cancer

The e+e-→3(π+π-), 2(π+π-π0) and K+K-2(π+π-) cross sections at center-of-mass energies from production threshold to 4.5 GeV measured with initial-state radiation

Abstract: We study the processes e^+e^- → 3(π^+π^-)γ, 2(π^+π^-π^0)γ and K^+K^-2(π^+π^-)γ, with the photon radiated from the initial state. About 20 000, 33 000 and 4000 fully reconstructed events, respectively, have been selected from 232 fb^(-1) of BABAR data. The invariant mass of the hadronic final state defines the effective e^+e^- center-of-mass energy, so that these data can be compared with the corresponding direct e^+e^- measurements. From the 3(π^+π^-), 2(π^+π^-π^0) and K^+K^-2(π^+π^-) mass spectra, the cross sections for the processes e^+e^- → 3(π^+π^-), e^+e^- → 2(π^+π^-π^0) and e^+e^- → K^+K^-2(π^+π^-) are measured for center-of-mass energies from production threshold to 4.5 GeV. The uncertainty in the cross section measurement is typically 6%–15%. We observe a structure at 1.9 GeV in both cross sections and a resonance structure with mass 1645 ± 0.008 GeV/c^2 and width 0.114 ± 0.014 GeV when the ω(782)η final state is extracted. We observe the J/ψ in all these final states and measure the corresponding branching fractions.

Observation of a New D(s) Meson Decaying to DK at a Mass of 2.86-GeV/c**2

Abstract: We observe a new D_s meson with mass (2856.6 +/- 1.5_{stat.} +/- 5.0_{syst.}) MeV/c^2 and width (48 +/- 7_{stat.} +/- 10_{syst.}) MeV decaying into D^0 K^+ and D^+K^0_S. In the same mass distributions we also observe a broad structure with mass (2688 +/- 4_{stat.} +/- 3_{syst.}) MeV/c^2 and width (112 +/- 7_{stat.} +/- 36_{syst.}) MeV. To obtain this result we use 240 fb^-1 of data recorded by the BaBar detector at the PEP-II asymmetric-energy e^+e^- storage rings at the Stanford Linear Accelerator Center running at center-of-mass energies near 10.6 GeV.

J/ψ production and nuclear effects for d+Au and p+p collisions at sNN=200GeV

Common Suppression Pattern of η and π0 Mesons at High Transverse Momentum in Au + Au Collisions at √sNN = 200GeV

Abstract: Inclusive transverse momentum spectra of eta mesons have been measured within p(T)=2-10 GeV/c at midrapidity by the PHENIX experiment in Au+Au collisions at root s(NN) = 200 GeV. In central Au+Au the eta yields are significantly suppressed compared to peripheral Au+Au, d+Au, and p+p yields scaled by the corresponding number of nucleon-nucleon collisions. The magnitude, centrality, and p(T) dependence of the suppression is common, within errors, for eta and pi(0). The ratio of eta to pi(0) spectra at high p(T) amounts to 0.40 < R-eta/pi(0)< 0.48 for the three systems, in agreement with the world average measured in hadronic and nuclear reactions and, at large scaled momentum, in e(+)e(-) collisions.

Randomized, Double-Blind, Active-Controlled Trial of Every-3-Week Darbepoetin Alfa for the Treatment of Chemotherapy-Induced Anemia

Abstract: Background: In the United States, darbepoetin alfa (Aranesp) is often used to treat patients with chemotherapy-induced anemia using weekly or every-2-week administration schedules. In Europe, darbepoetin alfa is used either weekly or in every-3-week dosing. The every-3-week schedule can be synchronized with many chemotherapy regimens, resulting in fewer visits and reducing burden to patients, but the safety and effi cacy of this regimen have not been clear. Methods: A randomized, double-blind, double-dummy, active-controlled phase 3 trial was performed in 110 European centers. Eligible patients (age ≥ 18 years) were anemic (hemoglobin level <11 g/dL), had a nonmyeloid malignancy, and were to receive at least 12 weeks of chemotherapy. Patients were randomly assigned 1:1 to darbepoetin alfa treatment every 3 weeks (500- μ g dose) or weekly (2.25- μ g/kg) for 15 weeks. We compared red blood cell transfusion incidence among the two arms from week 5 to the end of the treatment phase using a noninferiority study design. Noninferiority was determined if the upper limit of the 95% confi dence interval (CI) for the difference in blood transfusions between groups, calculated using Kaplan – Meier methods, did not exceed 12.5%, a margin based on previous placebo-controlled studies. Results: A total of 705 patients were randomly assigned, and 672 remained in the study at week 5. Fewer patients in the every3-week arm than in the weekly arm received blood transfusions from week 5 to the end of the treatment phase (unadjusted Kaplan – Meier estimates = 23% versus 30%, difference = − 6.8%; 95% CI = − 13.6 to 0.1). Percentages of patients achieving the target hemoglobin level ( ≥ 11 g/dL, consistent with evidence-based practice guidelines) were 84% (every 3 weeks) and 77% (weekly). The frequency of cardiovascular/thromboembolic adverse events was 8% in both groups, and safety was comparable. Conclusions: Patients with chemotherapy-induced anemia can safely and effectively be treated with 500 μ g of darbepoetin alfa every 3 weeks. [J Natl Cancer Inst 2006;98:273 – 84]

Search for B+ -> X(3872) K+, X(3872) -> J/psi gamma

Abstract: In a study of B+ --> J/psi gamma K+ decays, we find evidence for the radiative decay X(3872) --> J/psi gamma with a statistical significance of 3.4 sigma. We measure the product of branching fractions BF(B+ --> X(3872) K+).BF(X(3872) --> J/psi gamma) = (3.3 +/- 1.0 +/- 0.3) x 10^-6, where the uncertainties are statistical and systematic, respectively. We also measure the branching fraction BF(B+ --> chi_c1 K+) = (4.9 +/- 0.2 +/- 0.4) x 10^-4. These results are obtained from (287+/-3) million BBar decays collected at the Y(4S) resonance with the BaBar detector at the PEP-II B Factory at SLAC.

Unconventional dynamics in triangular Heisenberg antiferromagnet NaCrO2.

Abstract: We report magnetization, specific heat, muon spin rotation, and Na NMR measurements on the S=3/2 rhombohedrally stacked Heisenberg antiferromagnet NaCrO2. This compound appears to be a good candidate for the study of isotropic triangular Heisenberg antiferromagnets with very weak interlayer coupling. While specific heat and magnetization measurements indicate the onset of a transition in the range Tc approximately 40-50 K, both muon spin rotation and NMR reveal a fluctuating crossover regime extending well below Tc, with a peak of relaxation rate T1(-1) around T approximately 25 K. This novel finding is discussed within the context of excitations in the triangular Heisenberg antiferromagnets.

Study of the X(3872) and Y(4260) in B0→J/ψπ+π-K0 and B-→J/ψπ+π-K- decays

Abstract: We present results of a search for the X(3872) in B{sup 0}{yields}X(3872)K{sub S}{sup 0},X(3872){yields}J/{psi}{pi}{sup +}{pi}{sup -}, improved measurements of B{sup -}{yields}X(3872)K{sup -}, and a study of the J/{psi}{pi}{sup +}{pi}{sup -} mass region above the X(3872). We use 232x10{sup 6} BB pairs collected at the {upsilon}(4S) resonance with the BABAR detector at the PEP-II e{sup +}e{sup -} asymmetric-energy storage rings. The results include the 90% confidence interval 1.34x10{sup -6}

Analysis of 14 candidate genes for diabetic nephropathy on chromosome 3q in European populations: strongest evidence for association with a variant in the promoter region of the adiponectin gene.

Abstract: Linkage studies have mapped loci for diabetic nephropathy and associated phenotypes on chromosome 3q. We studied 14 plausible candidate genes in the linkage region because of their potential role in vascular complications. In a large-scale study of patients from Denmark, Finland, and France who have type 1 diabetes, 1,057 case and 1,127 control subjects, as well as 532 trios, were investigated for association with diabetic nephropathy. We analyzed 69 haplotype-tagging single nucleotide polymorphisms and nonsynonymous variants that were identified by sequencing. Polymorphisms in three genes, glucose transporter 2 (SLC2A2), kininogen (KNG1), and adiponectin (ADIPOQ), showed nominal association with diabetic nephropathy in single-point analysis. The T-allele of SLC2A2_16459CT was associated with a decreased risk of diabetic nephropathy (odds ratio 0.79 [95% CI 0.66-0.96], P = 0.016), whereas the T-allele of KNG_7965CT and the A-allele of ADIPOQ_prom2GA were associated with increased risk of nephropathy (1.17 [1.03-1.32], P = 0.016; 1.46 [1.11-1.93], P = 0.006, respectively). Analyses of the transmission disequilibrium test showed similar trends only for ADIPOQ_prom2GA with the overtransmission of the A-allele to patients with diabetic nephropathy (1.52 [0.86-2.66], P = NS) and of the G-allele to patients without diabetic nephropathy (0.50 [0.27-0.92], P = 0.026). The overall significance for this variant (nominal P = 0.011) suggests that ADIPOQ might be involved in the development of diabetic nephropathy.

Observation of an excited charm baryon Ωc* decaying to Ωc0γ

Abstract: We report the first observation of an excited singly-charm baryon OmegaC* (css) in the radiative decay OmegaC0 Gamma, where the OmegaC0 baryon is reconstructed in the decays to the final states Omega-pi+, Omega-pi+pi0, Omega-pi+pi-pi+, and Cascade-K-pi+pi+. This analysis is performed using a dataset of 230.7 fb$-1} collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The mass difference between the OmegaC* and the OmegaC0 baryons is measured to be 70.8 +/- 1.0 (stat) +/- 1.1 (syst) MeV/c2. We also measure the ratio of inclusive production cross sections of OmegaC* and OmegaC0 in e+e- annihilation.

Jet properties from dihadron correlations in p+p collisions at s=200GeV

Abstract: The properties of jets produced in p+p collisions at root s=200 GeV are measured using the method of two-particle correlations. The trigger particle is a leading particle from a large transverse momentum jet while the associated particle comes from either the same jet or the away-side jet. Analysis of the angular width of the near-side peak in the correlation function determines the jet-fragmentation transverse momentum j(T). The extracted value, root =585 +/- 6(stat)+/- 15(sys) MeV/c, is constant with respect to the trigger particle transverse momentum, and comparable to the previous lower root s measurements. The width of the away-side peak is shown to be a convolution of j(T) with the fragmentation variable, z, and the partonic transverse momentum, k(T). The is determined through a combined analysis of the measured pi(0) inclusive and associated spectra using jet-fragmentation functions measured in e(+)e(-) collisions. The final extracted values of k(T) are then determined to also be independent of the trigger particle transverse momentum, over the range measured, with value of root =2.68 +/- 0.07(stat)+/- 0.34(sys) GeV/c.

Nuclear effects on hadron production in d + Au collisions at √sNN = 200 GeV revealed by comparison with p + p data

Abstract: PHENIX has measured the centrality dependence of midrapidity pion, kaon, and proton transverse momentum distributions in d+Au and p+p collisions at root s(NN) = 200 GeV. The p+p data provide a reference for nuclear effects in d+Au and previously measured Au+Au collisions. Hadron production is enhanced in d+Au, relative to independent nucleon-nucleon scattering, as was observed in lower energy collisions. The nuclear modification factor for (anti)protons is larger than that for pions. The difference increases with centrality but is not sufficient to account for the abundance of baryon production observed in central Au+Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC). The centrality dependence in d+Au shows that the nuclear modification factor increases gradually with the number of collisions encountered by each participant nucleon. We also present comparisons with lower energy data as well as with parton recombination and other theoretical models of nuclear effects on particle production.

Critical points and supersymmetric vacua, II: Asymptotics and extremal metrics

Abstract: Motivated by the vacuum selection problem of string/M theory, we study a new geometric invariant of a positive hermitian line bundle (L,h) → M over a compact Kahler manifold: the expected distribution K crit (z) of critical points dlog |s(z)|h = 0 of a Gaussian random holomorphic section s ∈ H 0 (M,L) with respect to h. It is a measure on M whose total mass is the average number N crit h of critical points of a random holomorphic section. We are interested in the metric dependence of N crit h , especially metrics h which minimize N crit h . We concentrate on the asymptotic minimization problem for the sequence of tensor powers (L N ,h N ) → M of the line bundle and their critical point densities K critN (z). We prove that K critN (z) has a complete asymptotic expansion in N whose coefficients are curvature invariants of h. The first two terms in the expansion of N crit hN are topological invariants of (L,M). The third term is a topological invariant plus a constantm 2 (depending only on the dimension m of M) times the Calabi functional R M � 2 dV olh, whereis the scalar curvature of the curvature form of h. We give an integral formula form 2 and show, by a computer assisted calculation, thatm 2 > 0 for m ≤ 3, hence that N crit hN is asymptotically minimized by the Calabi extremal metric (when one exists). We conjecture thatm 2 > 0 in all dimensions, i.e. that the Calabi extremal metric is always the asymptotic minimizer.

Measurement of the η and η′ transition form factors at q2=112GeV2

Abstract: We report a study of the processes e^+e^-→ηγ and e^+e^-→η′γ at a center-of-mass energy of 10.58 GeV, using a 232 fb^(-1) data sample collected with the BABAR detector at the PEP-II collider at SLAC. We observe 20_(-5)^(+6)ηγ and 50_(-7)^(+8)η′γ events over small backgrounds, and measure the cross sections σ(e^+e^-→ηγ)=4.5_(-1.1)^(+1.2)±0.3 fb and σ(e^+e^-→η′γ)=5.4±0.8±0.3 fb. The corresponding transition form factors at q^2=112 GeV^2 are q^2|F_η(q^2)|=0.229±0.030±0.008 GeV, and q^2|F_η′(q^2)|=0.251±0.019±0.008 GeV, respectively.

Measurement of the inclusive electron spectrum in charmless semileptonic B decays near the kinematic end point and determination of |Vub|

Abstract: We present a measurement of the inclusive electron spectrum in B → X_ueν decays near the kinematic limit for B → X_ceν transitions, using a sample of 88 × 10^6 BB pairs recorded by the BABAR detector at the Υ (4S resonance. Partial branching fraction measurements are performed in five overlapping intervals of the electron momentum; for the interval of 2.0 – 2.6 GeV/c we obtain ΔB (B → X_ueν) = (0.572 ± 0.041_(stat) ± 0.065_(syst)) × 10^(−3). Combining this result with shape function parameters extracted from BABAR measurements of moments of the inclusive photon spectrum in B → X_sγ decays and moments of the hadron-mass and lepton-energy spectra in B → X_clν decays we determine │Vub|= (4.44 ± 0.25 + 0.4_( exp−0.38SF) ± 0.22_(theory)) × 10^(−3). Here the first error represents the combined statistical and systematic experimental uncertainties of the partial branching fraction measurement, the second error refers to the uncertainty of the determination of the shape function parameters, and the third error is due to theoretical uncertainties in the QCD calculations.

Jet structure from dihadron correlations in d + Au collisions at √sNN = 200 GeV

Abstract: Dihadron correlations at high transverse momentum p(T) in d+Au collisions at root s(NN)=200 GeV at midrapidity are measured by the PHENIX experiment at the Relativistic Heavy Ion Collider. From these correlations, we extract several structural characteristics of jets: the root-mean-squared transverse momentum of fragmenting hadrons with respect to the jet root , the mean sine-squared of the azimuthal angle between the jet axes , and the number of particles produced within the dijet that are associated with a high-p(T) particle (dN/dx(E) distributions). We observe that the fragmentation characteristics of jets in d+Au collisions are very similar to those in p+p collisions and that there is little dependence on the centrality of the d+Au collision. This is consistent with the nuclear medium having little influence on the fragmentation process. Furthermore, there is no statistically significant increase in the value of from p+p to d+Au collisions. This constrains the effect of multiple scattering that partons undergo in the cold nuclear medium before and after a hard collision.

Search for T, CP, and CPT violation in B0-B0 mixing with inclusive dilepton events.

Abstract: The authors report the results of a search for T, CP and CPT violation in B{sup 0}-{bar B}{sup 0} mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B Factory. Using a sample of 232 million B{bar B} pairs, with a simultaneous likelihood fit of the same-sign and opposite-sign dileptons, they measure the T and Cp violation parameter |q/p|-1 = (-0.8 {+-} 2.7(stat.) {+-} 1.9(syst.)) x 10{sup -3}, and the CPT and CP parameters Im z = (-13.9 {+-} 7.3(stat.) {+-} 3.2(syst.)) x 10{sup -3} and {Delta}{Lambda} x Re z = (-7.1 {+-} 3.9(stat.) {+-} 2.0(syst.)) x 10{sup -3} ps{sup -1}. The statistical correlation between the measurements of Im z and {Delta}{Lambda} x Re z is 76%.

Single electrons from heavy-flavor decays in p+p collisions at s=200GeV

Abstract: The invariant differential cross section for inclusive electron production in p+p collisions at [FORMULA: SEE TEXT] has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over the transverse momentum range 0.4

Measurements of the absolute branching fractions of B-+/--> K-+/- Xc(c)over-bar-$

Abstract: We study the two-body decays of B^± mesons to K^± and a charmonium state X_cc in a sample of 210.5 fb^(-1) of data from the BABAR experiment. We perform measurements of absolute branching fractions B(B^±→K^±X_(cc)) using a missing mass technique, and report several new or improved results. In particular, the upper limit B(B^±→K^±X(3872)) 4.2% will help in understanding the nature of the recently discovered X(3872).

Measurement of Identified π0 and Inclusive Photon Second-Harmonic Parameter v2 and Implications for Direct Photon Production in √sNN = 200GeV Au + Au

Abstract: The azimuthal distribution of identified π0 and inclusive photons has been measured in VsNN=200 GeV Au+Au collisions with the PHENIX experiment at the Relativistic Heavy-Ion Collider (RHIC). The second-harmonic parameter (v2) was measured to describe the observed anisotropy of the azimuthal distribution. The measured inclusive photon v2 is consistent with the value expected for the photons from hadron decay and is also consistent with the lack of direct photon signal over the measured pT range 1–6 GeV/c. An attempt is made to extract v2 of direct photons.

Improved search for Ivμ→ve oscillation in a long-baseline accelerator experiment

Abstract: We performed an improved search for {nu}{sub {mu}}{yields}{nu}{sub e} oscillation with the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment, using the full data sample of 9.2x10{sup 19} protons on target. No evidence for a {nu}{sub e} appearance signal was found, and we set bounds on the {nu}{sub {mu}}{yields}{nu}{sub e} oscillation parameters. At {delta}m{sup 2}=2.8x10{sup -3} eV{sup 2}, the best-fit value of the K2K {nu}{sub {mu}} disappearance analysis, we set an upper limit of sin{sup 2}2{theta}{sub {mu}}{sub e}<0.13 at a 90% confidence level.

Energy loss of 1-50 keV H, He, C, N, O, Ne, and Ar ions transmitted through thin carbon foils

Abstract: Thin foils are used extensively in space plasma spectrometers, for example, for generation of a coincidence measurement via secondary electron emission in time-of-flight mass spectrometers and charge conversion of energetic neutral atoms (ENAs) in ENA imagers. An ion or neutral atom passing through the carbon foil experiences energy loss and straggling that can degrade the energy resolution or mass resolution. These effects need to be quantified in order to permit efficient instrument development and modeling. We present measurements of energy loss and energy loss straggling for H, He, C, N, O, Ne, and Ar ions between 1 and 50keV passing through carbon foils of different thicknesses (nominally between 0.5 and 3.0μg∕cm2). We derive empirical relationships for the energy loss and energy loss straggling as a function of foil thickness, ion species, and ion energy. In particular, below ∼10keV the energy loss of hydrogen seems to vary with foil thickness and the energy loss straggling seems to vary with the sq...
