Energy loss and $x_2$ scaling breakdown in $J/ψ$ nuclear production

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/39620In 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.5 pages, 2 figures.
