In the present work, we investigated the exclusive diffractive production of charmonium in pronton-nucleus collisions at the Large Hadron Collider (LHC) energies. Such exclusive production reactions possess a cleaner experimental signal than inclusive production once it is characterized by low multiplicity of particles between final produced state and the incident protons of collider beam. The considered theoretical framework was the perturbative model of Quantum Cromodynamics (QCD) for the Pomeron exchange. In particular, we have used the resolved Pomeron model which depends on the Pomeron flux and Pomeron parton distribution functions. The main goal is to provide predictions for the single diffractive cross section for the J/Psi meson production at the energies of 5.02 TeV and 8.8 TeV. We have shown that a measurement is feasible as the order of magnitude is 400 microbarns even absorption corrections. Furthermore, we analyze the ratio of the diffractive to inclusive cross section which allows theoretical uncertainties to be canceled, mostly those associated to approximations performed in inclusive case.

A recently proposed parametrization for the deep inelastic diffractive cross-section is used to describe the H1 '94 data. We find two possible solutions and discuss them in details.

A characteristic rise in the cross section near x = 1 has been reported for the single particle inclusive reaction π−p → π−X at Fermilab energies. Factorizable Regge amplitudes are used with a well-established analysis of the pp → pX peak to construct a parametrization of the triple-Regge couplings with αP(0) > 1 and to give a triple-Regge description of the meson + proton → meson + X cross section. Good agreement with the π−p → π−X data at 147 GeV/c is obtained and the peak is dominated by the triple-Pomeron component. This approach provides a reliable method for obtaining an estimate of the non-diffractive component. The inelastic diffractive cross section rises with energy and is found to account for most of the observed rise in σtot(π±p). The procedure is extended to K±p → K±X.
