Resumen | 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 pp̄ 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, σ eff=2.2±0.7(stat)±0.9(syst) mb. |
