BRAHMS results in the context of saturation and quantum evolution
Abstract
We report BRAHMS results from RHIC d+Au and p+p collisions at Sqrt(s_NN)=200GeV. A remarkable change in the nuclear modification factor RdAu is seen as the pseudorapidity of the detected charged hadrons changes from zero at mid-rapidity to 3.2 at the most forward angle studied during the 2003 run. For pseudorapidity eta>1 the suppression of the Rcp factor is more pronounced in the sample of central events in contrast to the behavior at mid-rapidity where the central events show higher enhancement compared to the semi-central sample. These results are consistent with a saturated Au wave function strongly affected by quantum evolution at higher values of rapidity.
