Generalized parton distributions (GPDs) enter QCD factorization theorems for hard exclusive reactions. They encode rich information about hadron partonic structure. We explore a possibility to constrain GPDs in experiments at LHC considering two different exclusive processes: the timelike Compton scattering and the photoproduction of heavy vector mesons.

Towards a determination of the low $x$ gluon via exclusive $J/\psi$ production
A Q0 cut accounts for numerically important power-suppressed corrections in exclusive J/ψ photoproduction coefficient functions, improving stability for low-x gluon constraints.
