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