Jet Quenching for Hadron-Tagged Jets in pA Collisions

Abstract

We calculate the medium modification factor IpA for 5.02 TeV p + Pb collisions. We use the Monte-Carlo Glauber model to determine the parameters of the quark-gluon plasma fireball in pA jet events. Our calculations show that the jet quenching effect for IpA turns out to be rather small. We have found that the theoretical IpA as a function of the underlying event charged multiplicity density, within errors, agrees with data from ALICE [1] for 5.02 TeV p + Pb collisions. However, the experimental errors are too large to draw a firm conclusion on the possible presence of jet quenching.
