description Studies of jet production can provide information about the properties of the hot and dense strongly interacting matter created in ultra-relativistic heavy-ion collisions. Specifically, measurement of strange particles in jets may clarify the role of fragmentation processes in the anomalous baryon to meson ratio at intermediate particle pT that was observed in PbPb and, to a lesser extent, in pPb collisions. In this contribution, measurements of the pT spectra of Lambda and Antilambda baryons and K0s mesons produced in association with charged jets in PbPb collisions at sqrt(sNN)=2.76 TeV and pPb collisions at sqrt(sNN)=5.02 TeV are presented. The analysis is based on data which was recorded by ALICE at the LHC, exploiting its excellent particle identification capabilities. The baryon meson ratios of the spectra of strange particles associated with jets are studied for different event activities in p-Pb and are restricted to central events in PbPb. A comparison to the ratios obtained for inclusive particles and for particles stemming from the underlying event as well as to PYTHIA simulations is shown.

Specifically, measurement of strange particles in jets may clarify the role of fragmentation processes in the anomalous baryon to meson ratio at intermediate particle p (T) that was observed in lead-lead (Pb–Pb) and, to a lesser extent, in proton-lead (p–Pb) collisions. In this contribution, measurements are presented of the p (T) spectra of $\Lambda (\bar \Lambda )$ baryons and ${\rm{K}}_{\rm{S}}^0$ mesons produced in association with charged jets in Pb–Pb collisions at $\sqrt {{s_{{\rm{NN}}}}} = 2.76{\rm{ TeV}}$ and p–Pb collisions at $\sqrt {{s_{{\rm{NN}}}}} = 5.02{\rm{ TeV}}$. The analysis is based on data recorded by ALICE at the LHC, exploiting its excellent particle identification capabilities. The baryon/meson ratios of strange particles associated with jets are studied for different event activities in p–Pb collisions and are restricted to central events in Pb-Pb collisions. A comparison is shown to the ratios obtained for inclusive particle production and for particles stemming from the underlying event as well as to PYTHIA proton-proton (pp) simulations.arXiv:1502.01263oai:cds.cern.ch:19853382015-02-04
