Abstract
Di-hadron correlation technique is proved to be an impressive tool to probe the interplay between high \(p_{T}\) jets and the medium formed in high energy heavy ion collisions. Such interplay results in parton energy loss that significantly modify the jet structure and particle composition in jets. It has been argued that medium induced energy loss at high \(p_{T}\) would contribute to enhancement in both single inclusive and correlated yield at intermediate \(p_{T}\). RHIC results on two particle correlation is found to be consistent with energy loss picture however, correlated yield shows a particle species dependence. Baryon trigger yield is found to be suppressed compared to meson trigger at the most central collisions.This lack of correlated yield has been attributed to anomalous baryon enhancement that involves non perturbative processes like quark coalescence. Similar baryon to meson enhancement has been observed at LHC energy. Here we have presented correlated yield associated to a proton (baryon) and pion (meson) trigger from the events generated from String Melting (SM) version of A Multi Phase Transport model (AMPT) at Pb-Pb 2.76 TeV. Near side jet-like yield associated to a proton trigger is suppressed compared pion trigger at most central collisions. Suppression of small angle correlated yield has been discussed in the context of quark coalescence implemented in SM version of AMPT model.
