Elliptic flow of identified hadrons in [formula presented] collisions at [formula presented]

Abstract: The anisotropy parameter (v(2)), the second harmonic of the azimuthal particle distribution, has been measured with the PHENIX detector in Au+Au collisions at roots(NN)=200 GeV for identified and inclusive charged particle production at central rapidities (eta 2 GeV/c, in marked contrast to the predictions of a hydrodynamical model. A quark-coalescence model is also investigated.

Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV

Abstract: The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 inverse picobarns of data collected in pp collisions at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria covering a wide range of physics analysis needs have been examined. For all considered selections, the efficiency to reconstruct and identify a muon with a transverse momentum pT larger than a few GeV is above 95% over the whole region of pseudorapidity covered by the CMS muon system, abs(eta)<2.4, while the probability to misidentify a hadron as a muon is well below 1%. The efficiency to trigger on single muons with pT above a few GeV is higher than 90% over the full eta range, and typically substantially better. The overall momentum scale is measured to a precision of 0.2% with muons from Z decays. The transverse momentum resolution varies from 1% to 6% depending on pseudorapidity for muons with pT below 100 GeV and, using cosmic rays, it is shown to be better than 10% in the central region up to pT = 1 TeV. Observed distributions of all quantities are well reproduced by the Monte Carlo simulation.

The new age of MOFs and of their porous-related solids

Abstract: The discovery of Metal–Organic Frameworks, and porous polymers, at the end of the eighties represented a revolution in chemistry. This rapidly incited an increasing number of researchers to participate in this new field, due to the immense chemical and structural possibilities this family of materials offers for imaginative chemists. The unique combination of organic and inorganic moieties, mostly arranged in a crystallized three dimensional manner, afforded the opportunity to create a new class of porous solids, potentially much more attractive or complementary to the well-known zeolites, clays or activated carbons, due to the quasi-infinite richness of the inorganic parts (ions, clusters, chains. . .) and the variability of the linkers involved in the structures. The first age essentially concerned the chemical study of the assembly of the inorganic and organic building blocks associated with the structural determination of the resulting crystal. The second age, largely inspired by the properties of the traditional porous a Institut Charles Gerhardt Montpellier UMR 5253 CNRS ENSCM, Université Montpellier, Place E.
