Directed and Elliptic Flow at RHIC
We present the directed flow measurement () from Au+Au collisions at
\sqrtsNN = 62 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 \sqrtsNN = 200 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.Comment: 6 pages, 4 figures. Proceeding for Hot Quark 04 conference Changes in
