Description
Recent measurements of two-particle correlations within jets in high-multiplicity pp collisions at √s = 13.6 TeV reveal flow-like patterns among jet constituents. Such effects were previously considered unique to heavy-ion collisions, suggesting that a hot, dense QCD medium may form even inside jets in small systems. As this medium hadronizes, substantial final-state hadronic interactions can persist, leading to significant modifications of short-lived resonance yields through (pseudo-)elastic scatterings with other hadrons after chemical freeze-out. To investigate this, we analyze yields of the short-lived K⁰ meson using high-multiplicity jets in pp collision data at √s = 13.6 TeV collected by the ALICE Collaboration during LHC Run 3. Charged-particle jets are reconstructed, and per-jet K⁰ yields are measured in and out of the jet cone. Comparing these yields for this resonance offers new insight into final-state hadronic interactions inside jets produced in small collision systems.
