Description
Recent experimental results on two-particle correlations within jets in high multiplicity pp collisions highlight a strong flow-like correlation among constituents.
This has brought to the hypothesis of a formation of a hot and dense QCD medium within those jets. This observation suggests new insights of particle interaction dynamics in pp collisions, previously thought to be exclusive to heavy-ion collisions.
A key feature of such medium formation is the modified production ratios of different particle species. This is particularly the case for short-lived, strongly decaying resonances, allowing for (pseudo-) elastic collisions with formed hadrons after chemical freeze-out once the medium cools down. In turn, this drastically alters the final-state yields of such particles.
To investigate this phenomenon, we analyze the yields of K and Φ mesons within high-multiplicity jets in pp collisions at √s = 13.6 TeV, using LHC Run 3 data from ALICE. The analysis utilizes charged-particle jets, and per-jet yields of K and Φ in and out of such jets. The focus on these specific particles is expected to provide valuable insights into the intricate dynamics of QCD medium creation and its influence on particle production mechanisms.
