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 \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\sqrt{s_{NN}} = 200$\end{document} 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.
