Description
Generalized color transparency (CT) is related to QCD factorization theorems
allowing one to express cross sections of hard processes with nuclei
in terms of nuclear parton distributions. In my talk, I will review
recent studies of generalized CT in coherent photoproduction of
J/psi mesons in ultraperipheral collisions (UPCs) of heavy ions at the LHC
focusing on the leading twist nuclear shadowing of the nuclear gluon
density at small x.
