${\rm K}_{\rm S}^{0}$ and $\Lambda$ Production in Charged Particle Jets in p--Pb Collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV with ALICE

Abstract

We study the production of ${\rm K}_{\rm S}^{0}$ mesons and $\Lambda$ baryons in jets in p--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV with ALICE at the LHC. The $p_{\rm T}$-differential density of the particles produced in jets is compared to the inclusive distributions and the $\Lambda/{\rm K}_{\rm S}^{0}$ ratio is reported in bins of multiplicity of the collisions. The hard scatterings are selected on an event-by-event basis using the anti-$k_{\rm T}$ clustering algorithm with resolution parameter $R=0.2,~0.3$ and $0.4$, reconstructed from charged particles with a minimum $p_{\rm T,jet}$ of $10$ (or $20$) GeV/$c$.
