Directed and Elliptic Flow at RHIC
Abstract
We present the directed flow measurement () from Au+Au collisions at GeV. Over the pseudorapidity range we have studied, which covers from -1.2 to 1.2 and , the magnitude of for charged particles is found to increase monotonously with pseudorapidity for all centralities. No `` wiggle'', as predicted by various theoretical models, is observed at midrapidity. Elliptic flow () from moderate high particles () at GeV is presented as a function of impact parameter. It is found that models that are based on {\it jet quenching} alone appear to underpredict at moderate high , while the model that incorporates both, recombination and fragmentation, describes the data better.
