Abstract
We study the effect of the nucleon meson cloud on centrality dependence of the jet nuclear modification factor RpA. We find that the meson–baryon Fock components may lead to a noticeable deviation of RpA from unity. Our results for RpA 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.
