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

摘要

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. (C) 2004 Elsevier B.V.
