Transverse Radial Expansion and Directed Flow

Abstract

The effects of an interplay of radial expansion of the thermalized system created in a heavy ion collision and directed flow are discussed. It is shown that the study of azimuthal anisotropy of particle distribution as a function of rapidity and transverse momentum could reveal important information on both radial and directed flow.
