Small x Gluons in Nuclei and Hadrons
arXiv:hep-ph/9902411 · doi:10.1103/PhysRevD.60.054016
Abstract
We numerically study the effects of high gluon density at small x on the evolution of gluon distribution function in both hadrons and nuclei. Using a newly derived, Wilson renormalization group-based evolution equation which includes n to 1 gluon ladder fusion, we find significant reduction in nuclear gluon distribution function for large nuclei at zero impact parameter at energies relevant for RHIC and LHC experiments.
