Description
We present high p_{T} pion, proton, kaon, and rho spectra measured
with the STAR experiment in p+p and Au+Au collisions at
200 GeV. We find the kaon/pion ratio to be enhanced
in Au+Au 200 GeV collisions relative to p+p 200 GeV collisions at p_T
6 GeV/c. The enhancement persists until p_{T} ~ 11 GeV/c for
central Au+Au 200 GeV collisions. We also show R_{AA} measured at the
same center of mass of energy, and find kaon and proton R_{AA} to be
higher than pion R_{AA} at pT > 6 GeV/c. Implications for medium
induced modifications of jet chemistry will be discussed.
