On the Production of J/ψ-Mesons in Pion–Nucleus Collisions

The processes of J /ψ-mesons production in pion–nucleus collisions are considered. For the determination of the inclusive spectra π A → J /ψ X , the model was used which takes into account the energy losses of hard gluons in the interactions of hadron states with the nucleus nucleons. The results of...

Description
Summary:The processes of J /ψ-mesons production in pion–nucleus collisions are considered. For the determination of the inclusive spectra π A → J /ψ X , the model was used which takes into account the energy losses of hard gluons in the interactions of hadron states with the nucleus nucleons. The results of calculations are presented together with the experimental data of NA3 Collaboration on π – Pt 195 → J /ψ X spectra at the incident pions energies of 150 and 280 GeV.
