Description
The exclusive vector meson production cross section is one of the most promising observables to probe the high energy regime of the QCD dynamics. In particular, the squared momentum transfer (t) distributions are an important source of information about the spatial distribution of the gluons in the hadron and about fluctuations of the color fields. In this contribution we present our recent results for the Run II of the LHC considering the presence of the gluon saturation effects. In particular, we present a comprehensive analysis of the t - spectrum measured in exclusive ρ, ϕ and J/Ψ photoproduction in pp and PbPb collisions at the LHC. We demonstrate that gluon saturation suppresses the magnitude of the cross sections and shifts the position of the dips towards smaller values of t. Moreover, we demonstrate that our predictions describe the recent LHC data.
