Geometric Anisotropy

We study the influence of spatial and dynamical anisotropies in relativistic heavy-ion collisions on the differential elliptic and triangular flows of charged hadrons and, simultaneously, on the second- and third-order oscillations of the femtoscopic radii. Calculations of Pb + Pb collisions at s = 2.76 TeV were done within the HYDrodynamics with JETs (HYDJET++) event generator, which allows one to investigate the role of each of the anisotropy kinds separately. It is found that the bare geometric anisotropy provides either the wrong sign of elliptic and triangular flows or out-of-phase oscillations of R2out and R2side, respectively. Dynamical anisotropy is able to describe qualitatively both characteristics correctly. For the correct quantitative description of the data, one has to employ both spatial and dynamical anisotropies.
