Abstract

We present spectra of charged pions and protons in 0-10% central Au + Au collisions at sqrt(s_{N N}) = 200 GeV at mid-rapidity (y = 0) and forward pseudorapidity (η = 2.2) measured with the BRAHMS experiment at RHIC. The spectra are compared to spectra from p + p collisions at the same energy scaled by the number of binary collisions. The resulting nuclear modification factors for central Au + Au collisions at both y = 0 and η = 2.2 exhibit suppression for charged pions but not for (anti-) protons at intermediate p_T. The over(p, ̄) / π^- ratios have been measured up to p_T ∼ 3 GeV / c at the two rapidities and the results indicate that a significant fraction of the charged hadrons produced at intermediate p_T range are (anti-) protons at both mid-rapidity and η = 2.2.
