We present here v$_2$ of identified and inclusive charged particles measured in the PHENIX central arm detector ($|\eta| < 0.35$) with respect to the reaction plane defined at $|\eta| = 3 \sim 4$ in 200 GeV Au+Au collisions. We find that…
We report PHENIX measurements of the correlation of a trigger hadron at intermediate transverse momentum (2.5<p_{T,trig}<4 GeV/c), with associated mesons or baryons at lower p_{T,assoc}, in Au+Au collisions at sqrt(s_NN) = 200 GeV. The jet…
Azimuthal correlations of high-pT charged hadron pairs from (di-)jet-fragmentation are studied at mid-rapidity in Au+Au collisions at vsNN=200 GeV. The distribution of jet-associated partner hadrons (1.0< pT <2.5 GeV/c) per trigger hadron…
We present the first measurement of directed flow ($v_1$) at RHIC. $v_1$ is found to be consistent with zero at pseudorapidities $\eta$ from -1.2 to 1.2, then rises to the level of a couple of percent over the range $2.4 < |\eta| < 4$. The…
