Strangeness production with respect to high momentum hadrons in pp and p-Pb collisions with ALICE at the LHC

Abstract

In order to understand strangeness production mechanisms, one can study the correlations of hadrons with hidden strangeness (e.g. the $\varphi$ meson) and open strangeness (${\mathrm{K}}_{\mathrm{S}}^0$, $\Lambda$ and $\bar{\Lambda }$) in hard (jet) processes and in soft (bulk) processes. Two-particle angular correlations with ${\mathrm{K}}_{\mathrm{S}}^0$ triggers allow for the study of fragmentation in pp collisions as a function of multiplicity. Similarly, correlations with associated $\varphi$ mesons in p-Pb collisions allow both the jet and the underlying event components of strange particle production to be probed. Presented are ${\mathrm{K}}_{\mathrm{S}}^0$-h correlations measured by ALICE in pp collisions at $\sqrt{s}=13$ TeV, and h-$\varphi$ correlations measured in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV.
