Identified particle correlations at high p_T — •Lucia Anna Husova for the ALICE collaboration — Westfälische Wilhelms Universität, Münster, Germany

Due to high particle multiplicities produced in Pb-Pb collisions, it is difficult to reconstruct the low-energy jets in such a collision system. Instead the method of two-particle correlations can be used to study jet properties. This work reports results coming from two-particle correlations in pp collisions at 13 TeV collected at ALICE experiment at LHC, which can be used as basis for the same analysis by Pb-Pb collisions. Two-particle correlations were done with identified and unidentified trigger particles at high p_T up to 15 GeV/c. Strange V⁰ particles K_S⁰,Λ and Λ were chosen, because of their good reconstruction also at high p_T. The per trigger yield at near and away side was studied as a function of p_T trigger particle and the collision multiplicity. The dependace of the yield on the trigger particle at the near side will be discussed.
