Cold nuclear matter effects on jet suppression in heavy-ion collisions

These proceedings discuss the sensitivity of the nuclear modification factor R(AA) of fully reconstructed jets to cold nuclear matter effects. To test the parton energy loss interpretation of the observed R(AA) of ∼0.3, obtained from reconstructed jets in Pb–Pb collisions at $\sqrt{{s}_{{\rm{NN}}}}$ = 2.76 TeV, we measured the inclusive jet production in minimum bias p–Pb collisions at $\sqrt{{s}_{{\rm{NN}}}}$ = 5.02 TeV for resolution parameters R=0.2 and 0.4. The reconstructed jets incorporate the neutral and charged energy component and cover a momentum range ${p}_{\rm{T}}^{{\rm{jet}}}$ = 20-90 GeV. The comparison of the jet yield to PYTHIA simulations shows no significant depletion in the measured jet cross section attributed to cold nuclear matter effects present in p–Pb collisions.
