Previous measurements have shown that the away-side yield is suppressed in heavy-ion collisions. We present measurements of the away-side suppression as a function of transverse momentum and centrality in Cu+Cu and Au+Au collisions.

The scaling with charged particle multiplicity of the apparent system volume at final interaction is studied for the RHIC energy domain.

Finally, combining all of the above scaling and normalizations, we observe a near-universal scaling, with the exception of the Cu+Cu data at 62.4 GeV, of vsub2/sub/(nsubq/sub∙????????Nsup1/3/supsubpart/sub) vs KEsubT/sub/n

This is an important finding because hadronic jet quenching through energy loss is expected to be accompanied by a broadening effect.

We study the beam-energy and system-size dependence of ? meson production (using the hadronic decay mode ? → K+K−) by comparing the new results from Cu + Cu collisions and previously reported Au + Au collisions at √s{sub NN} = 62.4 ...

Recent data from RHIC suggest novel nuclear effects in the production of high p{sub T} hadrons. We present results from the STAR detector on high p{sub T} angular correlations in Au+Au and p+p collisions at (square root)S = 200 GeV/c.

Measurements of anisotropic flow of inclusive charged hadrons and identified +-p, +-K, p and ̄ p produced at midrapidity in asymmetric Cu+Au collisions at sqrt(sNN) = 200 GeV are presented.

At sufficiently high temperatures and densities quarks and gluons exist in a deconfined state called Quark Gluon Plasma (QGP).

We present the results of an elliptic flow, v2, analysis of Cu+Cu collisions recorded with the STAR detector at RHIC at √s{sub NN} = 62.4 and 200 GeV.

In this study, dihadron correlations are analyzed in \(\sqrt{s_{\mathrm{NN}}}=200\) GeV d+Au collisions classified by forward charged particle multiplicity and zero-degree neutral energy in the Au-beam direction.
