Abstract

We report evidence for the simultaneous production of J/ψ and ϒ mesons in 8.1  fb−1 of data collected at s√=1.96  TeV by the D0 experiment at the Fermilab pp¯ Tevatron Collider. Events with these characteristics are expected to be produced predominantly by gluon-gluon interactions. In this analysis, we extract the effective cross section characterizing the initial parton spatial distribution, σeff=2.2±0.7(stat)±0.9(syst)  mb.
