    Abstract

    We present transverse momentum spectra of unidentified charged hadrons at two pseudo-rapidities (η = 0, 2.2) as well as the first results on identified negatively charged pions at rapidity 2.2 from Au+Au collisions at √SNN = 200 GeV. The high pT yields of charged hadrons in the most central collisions show a strong suppression when compared to expected binary-scaled yields from nucleon-nucleon collisions or semi-peripheral collisions. The π spectra at forward rapidity (y = 2.2) also indicate a clear suppression of high pTπ yields in central collisions. PACS: 25.75.Dw Particle and resonance production
