Exploring the hadrochemistry of jet energy loss in ALICE

Energetic partons lose energy in the quark-gluon plasma (QGP) medium and then fragment into showers of particles called jets. It has been observed that this lost energy is mainly transferred to low-energy particles at large angles with respect to the jet axis. However, the particle composition of this transferred jet energy loss is not yet well understood. It has been predicted that the jet hadrochemical composition will be modified due to the QGP medium.

The ALICE experiment is ideally suited to explore this due to its excellent particle identification (PID) at low transverse momentum. This study will add insight to the question of the particle-type dependence of the jet energy loss by using the ALICE PID subdetectors to investigate the jet quenching hadrochemistry. In this talk, I will present studies towards comparing species-dependent particle kinematics in pp and Pb–Pb collisions at √s_NN = 5.02 TeV within a jet and the bulk. This study aims at disentangling the potential effects of modified jet fragmentation in the medium from bulk effects.
