Measurements of jet quenching via hadron+jet correlations in Pb-Pb and high-particle multiplicity pp collisions with ALICE
Original language description
Semi-inclusive measurements of hadron-jet acoplanarity are utilized to search for jet quenching effects in the 0-10% most central Pb-Pb collisions at vsNN = 5.02 TeV and the high-multiplicity pp collisions at vs = 13 TeV. In the Pb-Pb system, where quark-gluon plasma formation is established, a narrowing and suppression of the acoplanarity is observed relative to the PYTHIA-simulated pp reference. In contrast, the acoplanarity distributions that were measured in the high-multiplicity pp events exhibit a marked broadening and suppression with respect to the analogous distributions obtained from the minimum bias events. The observed features are, however, qualitatively reproduced by the PYTHIA 8 Monte Carlo event generator, which does not incorporate jet quenching. The PYTHIA simulations reveal that the observed suppression and broadening are the consequence of a bias induced by the ALICE high-multiplicity trigger, which increases the probability to observe a high-pT recoil jet in the acceptance of the forward trigger detectors and which biases toward multi-jet final states.
