Elliptical Flows in Reggeon Theory

摘要

A new mechanism for the generation of an azimuthal anisotropy of particles produced in heavy-ion collisions is analyzed. An analysis is performed within Reggeon theory and is general. The resulting effect can be interpreted in terms of the partonic structure of a fast nucleus. This mechanism can contribute significantly to the observed value of the elliptic flow v_2. The dynamics in question differs significantly from a standard mechanism of the collective motion of a hadron medium after a collision.
