Prospects of angular correlation studies of identified hadrons in the LHC Run 3 with the ALICE experiment

Abstract

The study of angular correlations of identified hadrons makes it possible to understand the impact of different processes that contribute to the hadronization mechanism in heavy-ion collisions and small collision systems. Depending on the quark composition and the system properties, the angular correlations exhibit different shapes. The mechanism of hadron production is non-perturbative, and because of that, only phenomenological models can be used. Those models still fail to fully describe hadron production. In particular, angular correlations for like-sign baryons are not reproduced by the models. The upgraded ALICE detector and the new analysis framework allow for precise measurements of baryon angular correlations which provide stronger constraints on the hadronization mechanisms.
