Abstract

Complementary to jet reconstruction, two-particle correlations in Δη and Δϕ can be used to study jets, in particular, their particle composition. While in Pb–Pb collisions, this is done to characterize the quark-gluon plasma, pp and p–Pb collisions serve as a reference and are of interest on their own for their input into the understanding of particle production mechanisms. Recent ALICE results on the production of strange particles in small systems (pp and p-Pb collisions) reveal the possibility of having similar strange hadron production mechanisms in all collision systems. We study the production mechanism of strange K0S meson in jets via two-particle correlations between the K0S and charged primary hadrons (h) in -pp collisions at √s = 13 TeV collected with the ALICE experiment at the LHC. In this paper, the per-trigger yields of K0S and charged hadrons will be presented on both the near-side and away-side of the h-K0S and K0S- h correlation functions. These yields will be shown depending on the transverse momenta of the trigger and associated particles, as well as on the event multiplicity. Moreover, the ratios of these yields to the yields extracted from the h-h correlation function will be shown. In addition, a comparison to different MC generators will be presented, which will allow us to better understand strangeness production in jets.
