The elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity (|y| < 0.7) is measured in Pb–Pb collisions at √sNN = 2.76 TeV with ALICE at the LHC. The particle azimuthal distribution with respect to the reaction plane can be parametrized with a Fourier expansion, where the second coefficient (v2) represents the elliptic flow. The v2 coefficient of inclusive electrons is measured in three centrality classes (0–10%, 10–20% and 20–40%) with the event plane and the scalar product methods in the transverse momentum (pT) intervals 0.5–13GeV/c and 0.5–8GeV/c, respectively.

Abstract: The measurement of prompt D-meson production as a function of multiplic- ity in p–Pb collisions at √sNN = 5.02TeV with the ALICE detector at the LHC is re- ported. D0, D+ and D∗+ mesons are reconstructed via their hadronic decay channels in the centre-of-mass rapidity range −0.96 < ycms < 0.04 and transverse momentum interval 1 < pT < 24 GeV/c. The multiplicity dependence of D-meson production is examined by either comparing yields in p–Pb collisions in different event classes, selected based on the multiplicity of produced particles or zero-degree energy, with those in pp collisions ...Daha fazlası
We report on results obtained with the event-shape engineering technique applied to Pb-Pb collisions at sNN = 2.76 TeV. By selecting events in the same centrality interval, but with very different average flow, different initial-state conditions can be studied. We find the effect of the event-shape selection on the elliptic flow coefficient v2 to be almost independent of transverse momentum pT, which is as expected if this effect is attributable to fluctuations in the initial geometry of the system. Charged-hadron, -pion, -kaon, and -proton transverse momentum distributions are found to be har ...Daha fazlası
Housing is a physical space where man finds himself from the moment a person comes to the World, the first steps are taken in the development of personality and selfness, the rules of social relations and social values are acquired and reproduced. It is the most important place to eat, to sleep, to get personal needs, shortly, to live in [1]. From the former time to daily time, these places are changing and developing day by day with many effects such as living conditions, environmental conditions, political interactions, aesthetic, climate conditions and population increase.

Abstract We present results on transverse momentum (pt) and rapidity (y) differential production cross sections, mean transverse momentum and mean transverse momen- tum square of inclusive J/ψ and ψ(2S) at forward rapid- ity (2.5 < y < 4) as well as ψ(2S)-to-J/ψ cross section ratios. These quantities are measured in pp collisions at cen- ter of mass energies √s = 5.02 and 13 TeV with the ALICE detector. Both charmonium states are reconstructed in the dimuon decay channel, using the muon spectrometer. A com- prehensive comparison to inclusive charmonium cross sec- tions measured at √s = 2.76, 7 ...Daha fazlası
We report a precise measurement of the J=ψ elliptic flow in Pb-Pb collisions at sNN 1⁄4 5.02 TeV with the ALICE detector at the LHC. The J=ψ mesons are reconstructed at midrapidity (jyj < 0.9) in the dielectron decay channel and at forward rapidity (2.5 < y < 4.0) in the dimuon channel, both down to zero transverse momentum. At forward rapidity, the elliptic flow v2 of the J=ψ is studied as a function of the transverse momentum and centrality. A positive v2 is observed in the transverse momentum range 2 < pT < 8 GeV=c in the three centrality classes studied and confirms with higher statistics ...Daha fazlası
We report measurements of the inclusive J/ψ yield and average transverse momentum as a function of charged-particle pseudorapidity density dNch/dη in p–Pb collisions at √sNN = 5.02 TeV with ALICE at the LHC. The observables are normalised to their corresponding averages in non-single diffractive events. An increase of the normalised J/ψ yield with normalised dNch/dη, measured at mid-rapidity, is observed at mid-rapidity and backward rapidity. At forward rapidity, a saturation of the relative yield is observed for high charged-particle multiplicities. The normalised average transverse momentum ...Daha fazlası
The production of K∗(892)0 and φ(1020) mesons in proton-proton (pp) and lead-lead (Pb-Pb) collisions at √sNN = 2.76 TeV has been analyzed using a high luminosity data sample accumulated in 2011 with the ALICE detector at the Large Hadron Collider (LHC). Transverse momentum (pT) spectra have been measured for K∗(892)0 and φ(1020) mesons via their hadronic decay channels for pT up to 20 GeV/c. The measurements in pp collisions have been compared to model calculations and used to determine the nuclear modification factor and particle ratios. The K∗(892)0/K ratio exhibits significant reduction fro ...Daha fazlası
