Abstract
By using Monte-Carlo implementations of -factorization formula with running-coupling BK unintegrated gluon distributions for nucleus-nucleus collisions, we compute higher order harmonic moments of the initial density distribution for both RHIC(Au+Au@200GeV) and LHC([email protected]) collisions. We study their sensitivity to the size of the valence parton distribution in the nucleon.
