| Özet |
| Event-by-event fluctuations in the elliptic-flow coefficient v 2 are studied in PbPb collisions at s NN= 5.02 TeV using the CMS detector at the CERN LHC. Elliptic-flow probability distributions p (v 2) for charged particles with transverse momentum 0.3< p T< 3.0 GeV/c and pseudorapidity| η|< 1.0 are determined for different collision centrality classes. The moments of the p (v 2) distributions are used to calculate the v 2 coefficients based on cumulant orders 2, 4, 6, and 8. A rank ordering of the higher-order cumulant results and nonzero standardized skewness values obtained for the p (v 2) distributions indicate non-Gaussian initial-state fluctuations. Bessel–Gaussian and elliptic power fits to the flow distributions are studied to characterize the initial-state spatial anisotropy. |
