Аннотация:The azimuthal anisotropy of particle distributions is one of the important observables that characterize collective effects at the initial stage of the formation and expansion of quark-gluon matter in collisions of relativistic nuclei. It is expect ed that an increase in energy from RHIC to LHC values will be accompanied by the growth of the azimuthal-anisotropy coefficient I (2) and the growth of nonflow effects (contribution of minijets and other correlations between particles). In the present st udy, methods for determining the azimuthal-anisotropy coefficient I (2) are analyzed on the basis of events simulated with the aid of the HYDJET generator for Pb + Pb collisions at the LHC energies, the contribution of nonflow effects being estimated. Th e accuracy of measuring the coefficient I (2) as a function the transverse momentum and pseudorapidity under experimental conditions at LHC is assessed.
