> TITLE:
> Centrality dependence of charged hadron production in
> deuteron + gold and nucleon + gold collisions at
> \sqrt{s_{NN}} = 200 GeV
> 
> ABSTRACT:
> We present transverse momentum (p_T) spectra of charged
> hadrons measured in deuteron-gold and nucleon-gold collisions
> at \sqrts = 200 GeV for four centrality classes. Nucleon-gold
> collisions were selected by tagging events in which a spectator
> nucleon was observed in one of two forward rapidity detectors.
> The spectra and yields were investigated as a function of the
> number of binary nucleon-nucleon collisions, \nu, suffered
> by deuteron nucleons.  A comparison of charged particle
> yields to those in p+p collisions show that the yield per
> nucleon-nucleon collision saturates with \nu for high
> momentum particles. We also present the charged hadron
> to neutral pion ratios as a function of p_T.
