Narrowing the uncertainty on the total charm cross section and its effect on the J/\psi\ cross section

TL;DR

This paper refines the estimate of the total charm cross section by analyzing parameter space and examines how these choices influence the energy dependence of the J/
31 cross section, improving understanding of their relationship.

Contribution

It introduces a systematic approach to constrain the total charm cross section and assesses its impact on J/
31 production predictions.

Findings

More precise charm cross section estimates

Quantified effect of parameter choices on J/
31 energy dependence

Enhanced understanding of charm and J/
31 production relationship

Abstract

We explore the available parameter space that gives reasonable fits to the total charm cross section to make a better estimate of its true uncertainty. We study the effect of the parameter choices on the energy dependence of the J/\psi\ cross section.
