Description
The recently measured centrality dependence of high energy jets in proton-lead collisions at the LHC is investigated. We conjecture that events with jets of very high energy (a few hundred GeV) are characterized by a suppressed number of soft particles thus shifting these events into more peripheral bins. This naturally results in the suppression (enhancement) of the nuclear modification factor, $R_{pA}$, in central (peripheral) collisions. Our calculations suggest that a moderate suppression of the order of $20\%$ can quantitatively reproduce the experimental data. We further propose an independent experimental test to verify this mechanism.
