Effect of a meson cloud on the jet nuclear modification factor in pA collisions

Abstract

We study the effect of the nucleon meson cloud on centrality dependence of the jet nuclear modification factor R pA. We find that the meson–baryon Fock components may lead to a noticeable deviation of R pA from unity. Our results for R pA show the same tendency as that observed by ATLAS in p + Pb collisions at √s = 5.02 TeV. The meson cloud suppresses the central jet events and enhances the peripheral jet events. However, quantitatively the effect is somewhat smaller than in the data.
