Title: Identified particle elliptic flow in Au+Au collisions at √(sNN) = 130 GeV.

Abstract

We report first results on elliptic flow of identified particles at midrapidity in Au+Au collisions at √(sNN)= 130 GeV using the STAR TPC at RHIC. The elliptic flow as a function of transverse momentum and centrality differs significantly for particles of different masses. This dependence can be accounted for in hydrodynamic models, indicating that the system created shows a behavior consistent with collective hydrodynamical flow. The fit to the data with a simple model gives information on the temperature and flow velocities at freeze-out.
