Abstract:

Processes of production of J/Ψ-mesons in pion–nucleus collisions are considered. For the determination of inclusive spectra πA → J/ΨX the model was used which takes into account energy losses of hard gluons in interactions of hadron states with nucleus nucleons. Results of calculations are presented together with experimental data of NA3 Collaboration on π–Pt195 → J/ΨX spectra at incident pions energies 150 and 280 GeV.
