Identified particle correlations at high pT — •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 pT up to 15 GeV/c. Strange V0 particles KS0,Λ and Λ were chosen, because of their good reconstruction also at high pT. The per trigger yield at near and away side was studied as a function of pT trigger particle and the collision multiplicity. The dependace of the yield on the trigger particle at the near side will be discussed.
