| Summary: | Abstract Exclusive $$J/\psi $$ J / ψ production is investigated in proton–proton collisions employing GPD approach with GK model. Three sets gluon density are used to calculate exclusive $$J/\psi $$ J / ψ production. The survival factors and equivalent photon approximation are applied to predict the exclusive $$J/\psi $$ J / ψ photoproduction in proton–proton collisions. The GPD method prediction gives a good agreement with the experimental data at LHCb. The exclusive $$J/\psi $$ 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 $$J/\psi $$ J / ψ cross sections in future proton–proton collisions. |
