Description
In order to understand strangeness and resonance production mechanisms, one can study the correlations of hadrons with hidden (e.g. the $\phi$ meson) and open strangeness ($K_{S}^{0}$, $\Lambda$ and $\bar{\Lambda}$) in hard (jet) processes and in soft (bulk) processes. Two-particle jet-like angular correlations with $\phi$ mesons in p-Pb collisions probe both the jet and the underlying event components of strange particle production. These studies can lead to insights into the observed enhancement in the $\phi$(1020)/$\pi$ ratio in p-Pb and high multiplicity pp collisions. Furthermore, the jet hadrochemistry is investigated by studying the ratios in the near and away-side jet peaks separately, and the results are compared to previously measured inclusive $\phi$/h yield ratios in different collision systems.
In this talk we present new measurements of the $\phi$/h ratio in jets as a function of multiplicity using jet-like hadron-$\phi$(1020) angular correlations in p-Pb collisions at $\sqrt{s_{NN}} = 5.02$ TeV. In order to further investigate strangeness production in jet processes, the hadron yields associated with high-momentum $K_{S}^{0}$ mesons and $\Lambda$ ($\bar{\Lambda}$) baryons are presented. Results will be shown for the near and away-side jet-like yields as a function of the associated particle momentum in pp collisions at $\sqrt{s} =$ 13 TeV and as a function of collision multiplicity.
