Evidence for Simultaneous Production of J/ψ and Υ Mesons
Journal Article
·
· Physical Review Letters
We report evidence for the simultaneous production of J/ψ and Υ mesons in 8.1 fb$$^{-1}$$of data collected at $$\sqrt{s}$$ = 1.96 TeV by the D0 experiment at the Fermilab $$p\bar{p}$$ 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.
