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 TeV.
The meson cloud suppresses the central jet events and
enhances the peripheral jet events.
But quantitatively the effect is somewhat smaller than in the
