摘要

Abstract

Mechanisms of \(K_{s}^{0}\) meson production can be studied using two-particle transverse-momentum (PT) correlations. The correlations between \(K_{s}^{0}\) mesons and hadrons produced in proton–proton interactions at center-of-mass energy of NN collisions of 10 GeV are considered in the Geant4/FTF and Pythia 6.4 models. The strong PT correlations between \(K_{s}^{0}\) mesons and Λ hyperons, K± mesons, and protons are observed. The study of the two-particle correlations is important to clarify the particle fragmentation functions and can be implemented at NICA SPD experiment.
