KS0 and Λ production in and outside jets in pp collisions at 13 TeV — •Lucia Anna Tarasovičová — Westfälis- che Wilhelms-Universität Münster, Germany
The contribution of jet fragmentation and soft processes to the strange hadron production in small collisions is still not understood well. Thus, angular correlations between particles can be utilised to study soft and hard fragmentation and production processes as well as the role of multiple parton interactions. Moreover, a study of the multiplicity dependence can further differentiate between the connection of bulk-particle and strangeness production in a more dense environment and the potential role of collective effects. In this talk, we present results on the two-particle correlation studies with respect to a primary charged hadron with high-pT (3-20 GeV/c) in pp collisions at 13 TeV measured with ALICE. The production of associated KS0 mesons, Λ hyperons and primary charged hadrons in jets and out of jets is studied as a function of the transverse momentum of the trigger and associated particles for several event-multiplicity classes. The yields will be compared among different associated particles and compared with PYTHIA and EPOS LHC event generators.
