Description
In addition to the final-state interactions, $J/ψ$ nuclear production might also be affected by parton energy loss. Using the upper limits from Drell-Yan data at SPS and Fermilab energies, we estimated energy loss contribution to $J/ψ$ production in p-A collisions. The results indicated that the effects might be sizeable at 200 GeV while remaining small at higher energies.
