High pT hadron spectra at high rapidity

We report the measurement of charged hadron production at different pseudorapidity values in deuteron+gold as well as proton-proton collisions at √SNN = 200 GeV at RHIC. The nuclear modification factors R dAu and R cp are used to investigate new behaviours in the deuteron+gold system as a function of rapidity and the centrality of the collisions, respectively.
