Název v původním jazyce

K-S(0)- and (anti-)Lambda-hadron correlations in pp collisions at root s=13 TeV

Popis výsledku v původním jazyce

Two-particle Azimuthal correlations are measured with the ALICE apparatus in pp collisions at root s = 13 TeV to explore strangeness- and multiplicity-related effects in the fragmentation of jets and the transition regime between bulk and hard production, probed with the condition that a strange meson (K-S(0)) or baryon (Lambda) with transverse momentum p(T) > 3 GeV/c is produced. Azimuthal correlations between kaons or Lambda hyperons with other hadrons are presented at midrapidity for a broad range of the trigger (3 < p(T)(trigg) < 20 GeV/c) and associated particle p(T) (1 GeV/c < p(T)(assoc) < p(T)(trigg)), for minimum-bias events and as a function of the event multiplicity. The near- and away-side peak yields are compared for the case of either K-S(0) or Lambda((Lambda) over bar) being the trigger particle with that of inclusive hadrons (a sample dominated by pions). In addition, the measurements are compared with predictions from PYTHIA 8 and EPOS LHC event generators.
