| contents | Exclusive $J/ψ$ production is investigated in proton-proton collisions employing GPD approach with GK model. Three
sets gluon density are used to calculate exclusive $J/ψ$ production. The survival factors and equivalent photon approximation
are applied to predict the exclusive $J/ψ$ photoproduction in proton-proton collisions. The GPD method prediction gives a good
agreement with the experimental data at LHCb.
The exclusive $J/ψ$ production is given in proton-proton collisions at RHIC and NICA.
These predictions of GPD approach can be employed to estimate the exclusive $J/ψ$ cross sections
in future proton-proton collisions. |
