Production of strange particles in charged jets in Pb--Pb and p--Pb collisions measured with ALICE
Résumé
Measurements of spectra of identified particles produced in jets represent an important tool for understanding the interplay of various hadronisation mechanisms which contribute to particle production in the hot and dense medium created in ultra-relativistic heavy-ion collisions. In this contribution, we present the measurements of the p T spectra of Λ baryons and KS0 mesons produced in charged jets in Pb–Pb collisions at sNN=2.76 TeV and in p–Pb collisions at sNN=5.02 TeV . The results are obtained with the ALICE detector at the LHC, exploiting the excellent particle identification capabilities of this experiment. Baryon-to-meson ratios of the spectra of strange particles associated with jets are studied in central collisions and are compared with the inclusive ratios.
