Gluon and quark distributions in large Nc QCD: theory vs. phenomenology
Abstract
We present the QCD analysis of the behavior of quark and gluon distributions in the limit of a large number of colors Nc. We show that the results agree qualitatively with the phenomenological data. In particular we draw attention to the fact that the polarized gluon distribution is suppressed at large Nc compared to the unpolarized one.
