TL;DR
This paper investigates how parton energy loss and pT-broadening in cold nuclear matter influence J/psi suppression in proton-nucleus collisions, with theoretical calculations matching experimental data and predictions for LHC energies.
Contribution
It provides a systematic analysis of parton energy loss effects on J/psi suppression, supporting pT-broadening as a key mechanism, and offers predictions for future collider experiments.
Findings
Good agreement between theory and E866, PHENIX data
pT-broadening and energy loss are dominant suppression effects
Predictions for J/psi and Upsilon suppression at LHC energies
Abstract
The effects of parton energy loss and pT-broadening in cold nuclear matter on the pT and centrality dependence, at various rapidities, of J/psi suppression in p-A collisions are investigated. Calculations are systematically compared to E866 and PHENIX measurements. The very good agreement between the data and the theoretical expectations further supports pT-broadening and the associated medium-induced parton energy loss as dominant effects in J/psi suppression in high-energy p-A collisions. Predictions for J/psi (and Upsilon) suppression in p-Pb collisions at the LHC are given.
