TLDR
In this paper, the nuclear modification factor derived from the inclusive yields of π0 mesons in p+p and d+Au collisions at center of mass energy sNN = 200 GeV and pseudorapidity = 4.00 (d beam direction) were reported.Abstract:
Measurements of the inclusive yields of π0 mesons in p+p and d+Au collisions at center of mass energy sNN = 200 GeV and pseudorapidity 〈η〉 = 4.00 (d beam direction) are reported. The yield for p+p collisions is in general agreement with perturbative QCD calculations. The d+Au yield is in agreement with a calculation which models the Au nucleus as a Color Glass Condensate for forward particle production. The nuclear modification factor derived from the inclusive yields is qualitatively consistent with models which suppress the gluon density in nuclei.read more
