Description
One of the most effective techniques for investigating the mechanism of baryon production is the study of angular correlations between two particles. Angular correlations represent a convolution of various physical processes, such as mini-jets, Bose-Einstein quantum statistics, conservation of momentum, resonances, and other phenomena that contribute to the unique behavior observed for different particle species.
Experimental results from proton-proton collisions at 7 TeV have revealed a pronounced anticorrelation — a phenomenon that has not been replicated by Monte Carlo models. This discovery triggered a series of studies that led to the formulation of what is now referred to as the “baryon correlation puzzle”.
In this work, the ALICE measurements of the angular correlation functions for identified particles (such as π±, K±, p–p̄, Λ–Λ̅ ) in pp, p–Pb, and Pb–Pb collisions at LHC energies of both Run 2 and Run 3 data across various multiplicity/centrality classes are presented. This new piece of the puzzle enhances the understanding of anticorrelation and raises new questions, prompting theorists to refine and expand existing theoretical models in search of new answers.
