Description
The research programme of the ALICE experiment at the LHC focuses on studies of the quark-gluon plasma, a state of matter where quarks and gluons are deconfined.
The measurement of jets originating from the fragmentation of hard-scattered partons in the early phases of a nuclear collision allows one to study parton energy loss in the hot and dense medium and provides constraints on theoretical predictions.
Measuring yields of ${\rm K_s^0}$, ${\Lambda}$ and $\overline{\Lambda}$ down to low momenta within jet cones can help to disentangle contributions from fragmentation and other hadronisation mechanisms such as parton recombination and coalescence.
In this poster we present the first results for ${\rm K_s^0}$, ${\Lambda}$ and $\overline{\Lambda}$ production associated with charged jets in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}} = 2.76$ TeV.
Neutral strange baryons and mesons are reconstructed from their topological decays into charged particles measured in the ALICE central tracking detectors.
A detailed systematic study of the strange-particle reconstruction efficiency in jet cones and the uncertainties related to jet energy resolution are discussed.
The analysis is performed in different centrality classes and the results are compared with inclusive particle production.
