Forward rapidity hadron production in deuteron–gold collisions from valence quarks

Abstract

We consider hadron production in deuteron–gold collisions at RHIC in the forward rapidity region. Treating the target nucleus as a color glass condensate and the projectile deuteron as a dilute system of valence quarks, we obtain good agreement with the BRAHMS minimum bias data on charged hadron production in the forward rapidity ( y = 3.2 ) and low p t region. We provide predictions for neutral pion production in minimum bias deuteron–gold collisions in the forward rapidity region, y = 3.8 , measured by the STAR Collaboration at RHIC.
