Abstract
Elliptic flow is among basic observables that characterize collective effects at the initial stage of formation of quark–gluon plasma in collisions of ultrarelativistic nuclei. The yields of neutral pions are measurable up to high transverse-momentum values; therefore, measurement of the elliptic flow for neutral pions is an efficient means for studying quark–gluon plasma. Measurement of the elliptic flow in asymmetric collision systems makes it possible to study the dependence of the elliptic flow on the initial geometry of the system. Two procedures for measuring the elliptic flow for neutral pions in the asymmetric collision system at the energy of GeV are considered.
