Nature of particles azimuthal anisotropy at low and high transverse momenta in ultrarelativistic A+A collisions
Abstract
LHC data on the correlations of the elliptic flow v2 of particles at low and high transverse momenta pT from Pb+Pb collisions at center-of-mass energy per nucleon pair sNN = 5.02 TeV are analyzed in the framework of the HYDJET++ model. This model includes soft and hard components which allows to describe the region of both low and high transverse momenta. The origin of v2 values in different pT regions is investigated at different centralities. It is shown that the experimentally observed correlations between v2 at low and high pT in peripheral lead-lead collisions is due to correlation of particles in jets.
