Shadowing of gluons in perturbative QCD: A comparison of different models
Jamal Jalilian-Marian, Xin-Nian Wang
Abstract
We investigate the different perturbative QCD-based models for nuclear shadowing of gluons. We show that in the kinematic region appropriate to RHIC experiment, all models give similar estimates for the magnitude of gluon shadowing. At scales relevant to LHC, there is a sizable difference between predictions of the different models.
