Monte Carlo simulations of Upsilon meson production

Original language description

Υ meson production dependence on charged particle multiplicity involves the interplay between soft and hard QCD processes. Normalised multiplicity dependence is a meaningful tool for understanding the particle production mechanisms. The observed strong increase may be explained by multi-parton interactions, string percolation or color glass condensate saturation effects. This paper presents Monte Carlo simulations of Υ meson production in proton-proton collisions at root ???? = 500 GeV with PYTHIA and Herwig generators. The aim of the simulations is to explore the dependence of normalised Υ meson yield on normalised event multiplicity. Herwig with ???? > 4 GeV/c shows a linear dependence of ????Υ/<????Υ> vs. ????ch/<????ch> for Upsilon ????T > 0 GeV/c, while both PYTHIA 8 and Herwig with ???? > 20 GeV/c show a stronger than linear dependence.
