TL;DR: In this article, a measurement of the exclusive e+ e- --> Lambda+_(c)Lambda-_(c)) cross section as a function of center-of-mass energy near the Lambda− threshold is reported.
Abstract: We report a measurement of the exclusive e+ e- -->Lambda+_(c)Lambda-_(c) cross section as a function of center-of-mass energy near the Lambda+_(c)Lambda-_(c) threshold. A clear peak with a significance of 8.2sigma is observed in the Lambda+_(c)Lambda-_(c) invariant mass distribution just above threshold. With an assumption of a resonance origin for the observed peak, a mass and width of M=[4634 (+8)_(-7)(stat)(+5)_(-8)(syst)] MeV/c(2) and Gamma_(tot)=[92 (+40)_(-24)(stat)(+10)_(-21)(syst)] MeV are determined. The analysis is based on a study of events with initial-state-radiation photons in a data sample collected with the Belle detector at the Upsilon(4S) resonance and nearby continuum with an integrated luminosity of 695 fb(-1) at the KEKB asymmetric-energy e+ e- collider.

TL;DR: In this article, the processes e+e-→J/ψD(*)D*D* were studied and a new charmonium-like state X(4160) was observed.
Abstract: We report a study of the processes e+e-→J/ψD(*)D(*). In J/ψD*D* we observe a significant enhancement in the D*D* invariant mass spectrum, which we interpret as a new charmoniumlike state and denote X(4160). The X(4160) parameters are M=(4156-20+25±15)MeV/c2 and Γ=(139-61+111±21)MeV. We also report a new measurement of the X(3940) mass and width: M=(3942-6+7±6) MeV/c2 and Γ=(37-15+26±8)MeV. The analysis is based on a 693fb-1 data sample recorded near the Υ(4S) resonance by the Belle detector at the KEKB asymmetric-energy collider. © 2008 The American Physical Society.

TL;DR: The Collins effect connects transverse quark spin with a measurable azimuthal asymmetry in the yield of hadronic fragments around the quark's momentum vector, which can be attributed to the fragmentation of primordial quarks with transverse spin components as discussed by the authors.
Abstract: The Collins effect connects transverse quark spin with a measurable azimuthal asymmetry in the yield of hadronic fragments around the quark's momentum vector. Using two different reconstruction methods we measure statistically significant azimuthal asymmetries for charged pion pairs in e+e- annihilation at center-of-mass energies of 10.52 GeV and 10.58 GeV, which can be attributed to the fragmentation of primordial quarks with transverse spin components. The measurement was performed using a data set of 547fb-1 collected by the Belle detector at KEKB improving the statistics of the previously published results by nearly a factor of 20. © 2008 The American Physical Society.

TL;DR: In this paper, the first observation of the decay of Ds1(2536)+→D+π-K+K 0 was made using 462fb-1 of e+e- annihilation data recorded by the Belle detector.
Abstract: Using 462fb-1 of e+e- annihilation data recorded by the Belle detector, we report the first observation of the decay Ds1(2536)+→D+π-K+. The ratio of branching fractions B(Ds1(2536)+→D+π-K+)B(Ds1(2536) +→D*+K0) is measured to be (3.27±0.18±0.37)%. We also study the angular distributions in the Ds1(2536)+→D*+KS0 decay and measure the ratio of D- and S-wave amplitudes. The S-wave dominates, with a partial width of ΓS/Γtotal=0.72±0.05±0.01. © 2008 The American Physical Society.

Abstract: We present the results of a study of the charmless vector-vector decay B-0 -> omega K*(0) with 657 X 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB e(+)e(-) collider. We measure the branching fraction to be B(B-0 -> omega K*(0)) = [1.8 +/- 0.7(stat) +/- 0.3(syst)] X 10(-6) with 3.0 sigma significance. We also perform a helicity analysis of the omega and K*(0) vector mesons, and obtain the longitudinal polarization fraction f(L)(B-0 -> omega K*(0)) = 0.56 +/- 0.29(stat)(-0.08)(+0.18)(syst). Finally, we measure a large nonresonant branching fraction B[B-0 -> omega K+ pi(-); M-K pi is an element of (0.755, 1.250) GeV/c(2)] = [5.1 +/- 0.7(stat) +/- 0.7(syst)] X 10(-6) with a significance of 9.5 sigma.

This analysis is based on 657×106 BB events collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. The measured branching fraction is (2.44±0.22±0.20)×10-5 and the charge asymmetry is A=0.022±0.085±0.016. The ratio of the branching fractions B(B±→ψ(2S)π±)/B(B±→ψ(2S)K±)=(3. 99±0.36±0.17)% is also determined. © 2008 The American Physical Society.

TL;DR: In this paper, a search for the decay B0→J/ψ, using a sample of 657×106 BB pairs collected with the Belle detector at the Υ(4S) resonance was performed.
Abstract: We report a search for the decay B0→J/ψ, using a sample of 657×106 BB pairs collected with the Belle detector at the Υ(4S) resonance. No statistically significant signal is found and an upper limit for the branching fraction is determined to be B(B0→J/ψ)<9.4×10-7 at 90% confidence level. © 2008 The American Physical Society.

TL;DR: In this paper, the authors present a measurement of the mixing parameter $y-CP$ using a flavor-untagged sample of $D^0\to K_S^0K^+K^-$ decays.
Abstract: We present a measurement of the $D^0$-$\overline{D}^0$ mixing parameter $y_{CP}$ using a flavor-untagged sample of $D^0\to K_S^0K^+K^-$ decays. The measurement is based on a 673 fb$^{-1}$ data sample recorded by the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. We find $y_{CP} = (0.21 \pm 0.63 ({\rm stat.})\pm 0.78 (\rm syst.) \pm 0.01(\rm model))%$.
TL;DR: In this article, the authors report on a search for the decay of the Cabibbo-Kobayashi-Maskawa phase with a Charmless mode with a ε > 0.9 degrees.
Abstract: We report on a search for the decay $B^0\to\rho^0\rho^0$ and other charmless modes with a $\pi^+\pi^-\pi^+\pi^-$ final state, including $B^0\to\rho^0\pi^+\pi^-$, non-resonant $B^0\to 4\pi^{\pm}$, $B^0\to\rho^0f_0(980)$, $B^0\to f_0(980)f_0(980)$ and $B^0\to f_0(980)\pi^+\pi^-$. These results are obtained from a data sample containing 657 million $B \overline B$ pairs collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We set an upper limit on $\mathcal{B}(B^0\to\rho^0\rho^0)$ of $1.0\times 10^{-6}$ at the 90% confidence level (C.L.). From our $B^0\to\rho^0\rho^0$ measurement and an isospin analysis, we determine the Cabibbo-Kobayashi-Maskawa phase $\phi_2$ to be $91.7 \pm 14.9$ degrees. We find excesses in $B^0\to \rho^0\pi^+\pi^-$ and non-resonant $B^0\to 4\pi^{\pm}$ with 1.3$\sigma$ and 2.5$\sigma$ significance, respectively. The corresponding branching fractions are less than $12.0 \times 10^{-6}$ and $19.3 \times 10^{-6}$ at the 90% C.L. In addition, we set 90% C.L. upper limits as follows: $\mathcal{B}(B^0\to\rho^0f_0(980))< 0.3 \times 10^{-6}$, $\mathcal{B}(B^0\to f_0(980)f_0(980))< 0.1 \times 10^{-6}$, and $\mathcal{B}(B^0\to f_0(980)\pi^+\pi^-)< 3.8 \times 10^{-6}$.
