Investigating jet-medium interaction using charge dependent three-particle correlation in high multiplicity p+Pb collisions at sqrt{s_(NN) } = 5.02 TeV

Although many observations in high multiplicity p+Pb collisions at the LHC indicate striking similarity to heavy ion collisions, no evidence of jet-medium interactions has been observed till date. We study the effect of jet-medium interaction on the charge dependent three-particle correlation in high multiplicity p+Pb collisions at $\sqrt{s_{NN} }$ = 5.02 TeV using EPOS 3 event generator. The short range component of the three-particle correlation is dominated by the jet fragmentation and has a unique charge dependence as observed in the minimum bias p+Au collisions at the RHIC energy. In EPOS 3, similar pattern has been observed in the lower multiplicity classes of p+Pb collisions where jet fragmentation plays the dominant role. Interestingly, the charge dependence of three-particle correlation gets diminished in the higher multiplicity classes of p+Pb collisions where the jet-medium interactions as implemented in EPOS 3 plays an important role. The current study can, therefore, provide possible ways to investigate the jet-medium interaction in high multiplicity classes of small collision systems at the LHC energies.
