Description
We propose to investigate at NICA exclusive vector mesons production, essentially $J/\Psi$ production which is dominated by a gluon GPDs. These reactions is similar to the corresponding process in lepton-proton scattering and determined by GPDs.
Investigation of the exclusive D-Y production in the proton-proton reaction determined by two GPDs effects is in progress incollaboration with O. Teryaev and P. Kroll.
We find that $d \sigma/(dQ^2 dt1 dt2) \sim 20-30 \mbox{pb/GeV}^6$ at small $t1, t2$ and $Q^2=5\mbox{GeV}^2$ at NICA energies. This reaction can be studied at NICA and give an additional excess to GPDs.
