Azimuthal angle \Delta\phi correlations are presented for charged hadrons from dijets for 0.4 < p_T < 10 GeV/c in Au+Au collisions at sqrt(s_NN) = 200 GeV. With increasing p_T, the away-side distribution evolves from a broad to a concave…
We have measured 2D autocorrelations for all charged hadrons in STAR with $p_{t}$ $>$ 0.15 GeV/c and $| \eta |$ $<$ 1 from Au+Au collisions at 62 and 200 GeV. The correlation structure is dominated by a peak centered at zero relative…
We present the results of the two-particle $\Delta\phi$ correlation between high $p_T$ $\pi^0$ and charged hadrons in Cu+Cu collisions at $\sqrt{s_{NN}} = 200$ GeV. Clear away-side jet signals are seen in central Cu+Cu collisions at all…
We present measurements of two-particle angular correlations between high-transverse-momentum ($2<p_T<11$ GeV/$c$) $\pi^0$ observed at midrapidity ($|\eta|<0.35$) and particles produced either at forward ($3.1<\eta<3.9$) or backward…

STAR has measured forward pi^0 production in p+p and d+Au collisions at sqrt{s_{NN}}=200 GeV. The p+p yield generally agrees with NLO pQCD calculations. The d+Au yield is strongly suppressed at <eta>=4.0, well below shadowing expectations.…
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…
A model is constructed for the origin of the double-humped structure found in the di-hahron azimuthal correlation on the away-side in heavy ion collisions. The parameters in the model are determined by fitting $\Delta\phi$ azimuthal…
