Measurement of longitudinal flow decorrelations in Pb+Pb collisions at √sNN =2.76 and 5.02 TeV with the ATLAS detector
Original language description
Measurements of longitudinal flow correlations are presented for charged particles in the pseudorapidity range |η|<2.4 using 7 and 470 upmub−1 of Pb+Pb collisions at sNN−−−√=2.76 and 5.02 TeV, respectively, recorded by the ATLAS detector at the LHC. It is found that the correlation between the harmonic flow coefficients vn measured in two separated η intervals does not factorise into the product of single-particle coefficients, and this breaking of factorisation, or flow decorrelation, increases linearly with the η separation between the intervals. The flow decorrelation is stronger at 2.76 TeV than at 5.02 TeV. Higher-order moments of the correlations are also measured, and the corresponding linear coefficients for the kth -moment of the vn are found to be proportional to k for v3 , but not for v2 . The decorrelation effect is separated into contributions from the magnitude of vn and the event-plane orientation, each as a function of η .n
