Abstract
Motivated by forthcoming pPb experiments at Large Hadron Collider which require both knowledge of gluon densities accounting for saturation and for processes at a wide range of p t we study basic momentum space evolution equations of high energy QCD factorization Solutions of those equations might be used to form a set of gluon densities to calculate observables in generalized high energy factorization Moreover in order to provide a framework for predictions for exclusive final states in pPb scattering with high p t we rewrite the equation for the high energy factorizable gluon density in a resummed form similarly to what has been done in 1 for the BK equation The resummed equation is then extended to account for colour coherence This introduces an external scale to the evolution of the gluon density and therefore makes it applicable in studies of final statesThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
