The inclusive J/ψJ/ψ production cross-section and fraction of J/ψJ/ψ mesons produced in B -hadron decays are measured in proton–proton collisions at √s = 7 TeV with the ATLAS detector at the LHC, as a function of the transverse momentum and rapidity of the [J over ψ], using 2.3 pb[superscript −1] of integrated luminosity. The cross-section is measured from a minimum pT of 1 GeV to a maximum of 70 GeV and for rapidities within |y, European Organization for Nuclear Research, United States.
