Account of energy losses of hard gluons in processes of J/ψ-meson production in proton–nucleus collisions

Processes of production of cc̅ -states in proton–nucleus collisions are considered. The model is proposed taking into account energy losses of hard gluons in inelastic interactions of hadron states with nucleus nucleons. Results of performed calculations on the A -dependence of inclusive spectra of...

Description
Summary:Processes of production of cc̅ -states in proton–nucleus collisions are considered. The model is proposed taking into account energy losses of hard gluons in inelastic interactions of hadron states with nucleus nucleons. Results of performed calculations on the A -dependence of inclusive spectra of pA → J /ψ X processes are presented together with FNAL E866 experimental data.
