Unintegrated gluon distribution of a nucleus and photon-jet correlations

Abstract

An impact parameter dependent unintegrated gluon distribution is constructed as a solution of a nonlinear evolution equation with realistic Glauber--Gribov input. Photon--jet correlations in the proton fragmentation region of pA collisions are proposed as a direct probe of the nuclear unintegrated glue.
