Nuclear modification factor in d + Au collisions: Onset of suppression in the color glass condensate
Physics Letters, Section B
(2004)
Abstract
We perform a quantitative analysis of the nuclear modification factor in deuteron-gold collisions R dAu within the Color Glass Condensate approach, and compare our results with the recent data from RHIC experiments. Our model leads to Cronin enhancement at mid-rapidity, while at forward rapidities it predicts strong suppression of R dAu at all PT due to low-x evolution. We demonstrate that our results are consistent with the data for dAu charged hadron spectra, R dAu and R CP recently reported for rapidities in the interval η=0-3.2 by the BRAHMS experiment at RHIC. We also make a prediction for R pA at mid-rapidity in pA collisions at the LHC.
