Double parton interaction: the values of $\sigma_{\rm eff}$

High Energy Physics - Phenomenology 2020-03-11 v2 High Energy Physics - Experiment

Abstract

In this letter we show that the two parton showers mechanism for J/ΨJ/\Psi production, that has been discussed in Ref.[28], leads to small values of σeff\sigma_{\rm eff} for the production of a pair of J/ΨJ/\Psi. We develop a simple two channel approach to estimate the values of σeff\sigma_{\rm eff}, which produces values that are in accord with the experimental data.
