This contribution focuses on two-particles angular correlation in pp collisions at √s = 13 TeV of identified particles and their antiparticles.
Studying the angular correlations is a useful and powerful tool for understanding the mechanism of particle production in collisions of hadrons and high-energy nuclei.
The correlations between two-particles in relative azimuth (Delta varphi) and pseudorapidity (Delta eta) exhibit different structures that arise from different physical mechanisms that create distinctive structures in Delta eta Delta varphi space.
Each of these effects contribute to the correlation function by showing individual behavior.
The main goal of this study is to decompose and quantify each physical contribution that influences the structure of the correlation functions.
