A multi-differential investigation of strangeness production in pp collisions with ALICE

TL;DR

This paper investigates how strangeness production in proton-proton collisions at the LHC depends on factors like multiplicity, effective energy, and jet activity, revealing strong energy dependence and transverse region dominance.

Contribution

It presents two multi-differential analyses linking strangeness production to multiplicity, energy, and jet activity, providing new insights into the mechanisms of strangeness enhancement.

Findings

Strangeness production depends strongly on effective energy.

Strangeness originates mainly from the transverse region relative to the leading jet.

Results enhance understanding of particle production mechanisms at the LHC.

Abstract

In these proceedings, two multi-differential analyses performed in pp collisions collected by the ALICE collaboration during the LHC Run 2 are presented. One investigates the dependence of strange particle production with multiplicity and effective energy, whereas the other clarifies how strangeness enhancement is correlated to the leading jet in the event. The results suggest that strangeness production at the LHC depends strongly on effective energy, and originates dominantly from the transverse region with respect to the leading jet direction.
