Scientific paper

I discuss double-diffractive (double-elastic) production of the $\eta'$ and $\eta_c$ mesons in the $pp \to p X p$ reaction within the formalism of unintegrated gluon distribution functions (UGDF). The contribution of $\gamma^* \gamma^* \to \eta'$ fusion is estimated. The distributions in the Feynman $x_F$ (or rapidity), transferred four-momenta squared between initial and final protons ($t_1$, $t_2$) and azimuthal angle difference between outgoing protons ($\Phi$) are calculated and discussed. The results are compared with the WA102 data. Predictions at higher energies are presented.
