Double parton interaction: the values of ${\sigma }_{\mathrm{eff}}$

Abstract

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