Centrality dependence of the pseudorapidity density distribution for charged particles in Pb–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present the charged-particle pseudorapidity density in Pb–Pb collisions at √sNN = 5.02 TeV in centrality classes measured by ALICE. The measurement covers a wide pseudorapidity range from −3.5 to 5, which is sufficient for reliable estimates of the total number of charged particles produced in the collisions. For the most central (0–5%) collisions we find 21400±1300, while for the most peripheral (80–90%) we find 230 ± 38. This corresponds to an increase of (27 ± 4)% over the results at √sNN = 2.76 TeV previously reported by ALICE. The energy dependence of the total number of charged partic ...Daha fazlası

Production of 4He and 4He in Pb–Pb collisions at √sNN = 2.76 TeV at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Results on the production of 4He and 4He nuclei in Pb–Pb collisions at √sNN = 2.76 TeV in the rapidity range | y |< 1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0–10% central events are found to be dN /dy4 He = (0.8 ± 0.4 (stat) ± 0.3 (syst)) × 10−6 and dN /dy4 He = (1.1 ± 0.4 (stat) ± 0.2 (syst)) × 10−6, respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (Tchem = 156 MeV) as for light hadrons. The measured ratio of 4He/4He is 1.4 ± 0.8 (stat) ± 0.5 (syst).
