This contribution presents the analysis of two-particle angular correlations of pions, kaons and protons performed in pp collisions with energy √s = 13 TeV, that were registered by the ALICE experiment at the LHC.
Angular correlations are used to describe a wide spectrum of physical phenomena observed in high-energy particle collisions.
The correlations between two-particles in relative azimuth Δφ and rapidity Δy exhibit different structures that arise from several physical mechanisms that create distinctive structures in the Δy Δφ space.
Each of these effects contribute to the correlation function by showing individual behavior (e.g. different shape of the structures, different dependence on pT and/or multiplicity).
The main goal is to disentangle mentioned physics effects and study how they depend on the multiplicity of the events.
