Observed dependence of flow symmetry plane in ultra-relativistic heavyion collisions on transverse momentum (pT) and pseudorapidity η is attributed to lumpy hot-spots raised by the fluctuations of the initial states. Studying different orthogonal modes of the same flow harmonic has been suggested as a promising way to explore this phenomena. Prediction of leading and sub-leading modes for elliptic and triangular flow for charged pions for PbPb collisions at the center-of-mass energy per nucleon pair of 2.76 TeV from HYDJET++ model are presented. Calculations are done by applying principal component analysis technique (PCA) on a long-range two-particle azimuthal correlations, requesting/Δη/> 2 gap in order to avoid non-flow effects. The results are shown as a function of transverse momentum in a range of 0.3 < pT < 3.0 GeV/c, pseudorapidity range of/η/< 2.4, and in a various centrality classes, from ultra-central events (0-0.2%) up to rather peripheral ones (50-60%). Obtained values are... compared with data measurement from the CMS experiment. Rather good agreement between the model and the experimental data is a step in a better understanding of the initial-state fluctuations and dynamics of QGP expansion. © 2018 Jagellonian University.
