Measurement of strange baryon production in charged-particle jets in pp and p-Pb collisions with ALICE

Abstract

The enhancement of the ratio of strange to non-strange hadrons with increasing charged-particle multiplicity density is often interpreted as a signature of the medium formed in heavy-ion collisions. However, this effect has also been observed in smaller systems, such as pp and p-Pb collisions. Understanding this effect requires a detailed description of the production mechanisms of strange hadrons in and out of jets. In this manuscript are presented published results on the production of ${\mathrm{K}}_{\mathrm{S}}^0$, $\Lambda (\bar{\Lambda })$, ${\Xi }^{\pm }$ and ${\Omega }^{\pm }$ hadrons in charged-particle jets and the underlying event in pp and p-Pb collisions measured by ALICE. In addition, a new analysis of in-jet fragmentation into $\Lambda$ and ${\mathrm{K}}_{\mathrm{S}}^0$ hadrons in pp collisions at $\sqrt{s}=13.6$ TeV using LHC Run 3 data is shown.
