We present high transverse momentum, $p_{T}$, pion ($\pi$), proton ($p$), kaon ($K$), and rho ($\rho$) spectra measured with the STAR experiment from p+p and Au+Au collisions with \sNN{200}. We find the $K/\pi$ ratio to be enhanced in Au+Au…

We demonstrate that the $p_T$ dependence of the $\eta/\pi^0$ ratio is universal within a few percent for high energy $p$+$p$, $p$+A and $d$+A collisions, over a broad range of collision energies. The $\eta/\pi^0$ ratio increases with $p_T$…

Multiple parton scatterings in high-energy p+A collisions involve multi-parton correlation inside the projectile and color coherence of multiple jets which will lead to nuclear modification of final hadron spectra relative to that in p+p…

Jet suppression has been observed in central heavy ion collisions. This suppression is attributed to partonic energy loss in the Quark Gluon Plasma (QGP) formed in such collisions. However, this measurement is influenced by all stages of…
