Event activity-dependence of jet production in p-Pb collisions at root S-NN=5.02 TeV measured with semi-inclusive hadron plus jet correlations by ALICE
Original language description
We report measurement of the semi-inclusive distribution of charged-particle jets recoiling from a high transverse momentum (p(T)) hadron trigger, for p-Pb collisions at root S-NN = 5.02 TeV, in p-Pb events classified by event activity. This observable has been measured in pp and Pb-Pb collisions at the LHC, providing a new probe to measure quenching. Jets are reconstructed from charged particle tracks using anti-K-t with R = 0.4 and low IR cutoff of jet constituents (PT,track > 0.15 GeV/c). The complex uncorrelated jet background is corrected by a data-driven approach. Recoil jet distributions are reported for 15 < p(Tjet)(ch), < 50 GeV/c. Events are classified by signal in the ALICE VOA detector, which measures forward multiplicity, and ZNA, which measures the number of neutrons at zero degrees. This self-normalized observable does not require scaling of reference distributions by (TPA), thereby avoiding the need for geometric modeling. We compare the trigger-normalized recoil jet yield for p-Pb collisions with different event activity to measure the effects of jet quenching in small
