Abstract

The study of energy and multiplicity dependence of strange hadron production in proton-proton collisions provides a powerful tool to understand similarities and differences between small and large collision systems. In these proceedings, recent ALICE preliminary results are presented, which contribute to a better understanding of the strangeness production in pp collisions at √s = 13 TeV. Multi-strange Ξ− and Ξ+ baryon yields are studied as a function of multiplicity and effective energy, i.e., the energy available for particle production in the event. The main novelty of this analysis is the introduction of a new effective energy estimator, which is based on the energy deposited in ALICE Zero Degree Calorimeters. Such a multi-differential approach allows disentangling initial and final-state effects in the strangeness production in pp collisions.
