Sažetak (engleski)
Results on the transverse spherocity dependence of light-favor particle production (π, K, p, ϕ, K∗0 , K0 S , Λ, Ξ) at midrapidity in high-multiplicity pp collisions at √ s = 13 TeV were obtained with the ALICE apparatus. The transverse spherocity estimator (S pT=1 O ) categorizes events by their azimuthal topology. Utilizing narrow selections on S pT=1 O , it is possible to contrast particle production in collisions dominated by many soft initial interactions with that observed in collisions dominated by one or more hard scatterings. Results are reported for two multiplicity estimators covering diferent pseudorapidity regions. The S pT=1 O estimator is found to efectively constrain the hardness of the events when the midrapidity (|η| < 0.8) estimator is used. The production rates of strange particles are found to be slightly higher for soft isotropic topologies, and severely suppressed in hard jet-like topologies. These efects are more pronounced for hadrons with larger mass and strangeness content, and observed when the topological selection is done within a narrow multiplicity interval. This demonstrates that an important aspect of the universal scaling of strangeness enhancement with fnal-state multiplicity is that high-multiplicity collisions are dominated by soft, isotropic processes. On the contrary, strangeness production in events with jet-like processes is signifcantly reduced. The results presented in this article are compared with several QCD-inspired Monte Carlo event generators. Models that incorporate a two-component phenomenology, either through mechanisms accounting for string density, or thermal production, are able to describe the observed strangeness enhancement as a function of S pT=1 O .
