Abstract

The inclusive J/ψ production cross-section and fraction of J/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/ψ, using 2.3 pb^(−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|<2.4 giving the widest reach of any measurement of J/ψ production to date. The differential production cross-sections of prompt and non-prompt J/ψ are separately determined and are compared to Colour Singlet NNLO^★, filled, Colour Evaporation Model, and FONLL predictions.

The authors would like to thank Jean-Philippe Lansberg and Ramona Vogt for providing theoretical predictions for prompt production and for useful discussions. They would also like to thank Matteo Cacciari for providing predictions for the B→J/ψX production cross-sections in the FONLL scheme. We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.
