Strangeness Production in Jets and Underlying Events in pp Collisions at $\sqrt{s}$ = 13 TeV with ALICE

Abstract

The production of ${\mathrm{K}}_{\mathrm{S}}^0$, $\Lambda$ and $\Xi$ is measured in jets and underlying events in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE detectors. The corresponding $\Lambda /{\mathrm{K}}_{\mathrm{S}}^0$ and $\Xi /\Lambda$ ratios are presented as a function of transverse momentum. The hard scatterings are tagged by charged-particle jets ,which are reconstructed with the anti-$k_{\mathrm{T}}$ algorithm using a resolution parameter $R$ = 0.4. The flow-like correlations and the enhanced production of multi-strange hadrons in small colliding systems may be described by soft components.
