High energy QCD: multiplicity dependence of quarkonia production

TL;DR

This paper presents a novel approach to understanding quarkonia production dependence on hadron multiplicity, using three-gluon fusion without assuming saturation scale dependence, successfully matching experimental data.

Contribution

It introduces a new model based on three-gluon fusion that explains the steep multiplicity dependence of quarkonia production without relying on saturation scale assumptions.

Findings

The model reproduces experimental multiplicity dependence of quarkonia production.

It shows that the dependence is steeper than hadron multiplicity.

The approach does not assume saturation scale dependence.

Abstract

In this paper we propose an approach which demonstrates the dependence of quarkoni production on the multiplicity of the accompanying hadrons. Our approach is based on the three gluons fusion mechanism, without assuming the multiplicity dependence of the saturation scale. We show, that we describe the experimental data, which has a dependence that is much steeper than the multiplicity of the hadrons.
