Multiplicity dependence of $\chi_{c}$ and $\chi_{b}$ meson production

Abstract

In this paper we analyze in detail the production of the χc\chi_{c} and χb\chi_{b} mesons in pppp collisions. Using the color dipole framework, we estimated the cross-sections in the kinematics of ongoing and forthcoming experiments, and found that our estimates are in reasonable agreement with currently available experimental data. We also analyzed the dependence on multiplicity of co-produced hadrons and found that it is significantly milder than that of SS-wave quarkonia. We expect that the experimental confirmation of this result could constitute an important test of our understanding of multiplicity enhancement mechanisms in the production of different quarkonia states.
