| Resumo(s): | 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 View the MathML sources=7 TeV with the ATLAS detector at the LHC, as a function of the transverse momentum and rapidity of the J/ψJ/ψ, using 2.3 pb−1 of integrated luminosity. The cross-section is measured from a minimum pTpT of 1 GeV to a maximum of 70 GeV and for rapidities within |y|<2.4|y|<2.4 giving the widest reach of any measurement of J/ψJ/ψ production to date. The differential production cross-sections of prompt and non-prompt J/ψJ/ψ are separately determined and are compared to Colour Singlet NNLO⋆NNLO⋆, Colour Evaporation Model, and FONLL predictions. |
