Studying strangeness and baryon production in small systems through $\Xi-$hadron correlations using the ALICE detector

These proceedings summarise recent measurements of angular correlations between the Ξ baryon and identified hadrons in pp collisions at √S = 13 TeV using the ALICE detector. The results are compared with both string-based (PYTHIA8 with extensions) and core-corona (EPOS-LHC) models, to improve our un...

description These proceedings summarise recent measurements of angular correlations between the Ξ baryon and identified hadrons in pp collisions at √S = 13 TeV using the ALICE detector. The results are compared with both string-based (PYTHIA8 with extensions) and core-corona (EPOS-LHC) models, to improve our understanding of strangeness and baryon production in small systems. The results favour baryon production through string junctions over diquark breaking, but the PYTHIA models fail at describing the relatively wide Ξ—strangeness jet peak, indicating stronger diffusion of strange quarks in data. On the other hand, EPOS-LHC is missing local conservation of quantum numbers, making it difficult to draw any conclusion about the core-corona model.
