Abstract

The transverse momentum dependence of nuclear modification factors R _dAu for charged hadrons produced in d + Au collisions at √s_NN=200 GeV, was investigated. A significant and systematic decrease of R_dAu with increase in rapidity was observed. The central-to-peripheral collisions ratio was observed to be larger than the semicentral-to-peripheral ratio at low pseudorapidity, suggesting the increased role of Cronin-like multiple scattering effects in more violent collisions. At forward pseudorapidity, the more central ratio is smallest, which indicates a suppression mechanism. The results show that the midrapidity enhancement and the forward rapidity suppression were more pronounced in central collisions.
