Abstract

In this letter we show that the two parton showers mechanism for J/Ψ production, that has been discussed in Ref. [23], leads to small values of σeff for the production of a pair of J/Ψ. We develop a simple two channel approach to estimate the values of σeff, which produces values that are in accord with the experimental data.
