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 func- tion of the transverse momentum and rapidity of the J/ψ, using 2.3 pb−1 of integrated luminosity. The cross-sectionismeasuredfromaminimumpT of1GeVtoamaximumof70GeVandforrapiditieswithin |y| < 2.4 giving the widest reach of any measurement of J/ψ production to date. The differential produc- tion cross-sections of prompt and non-prompt J /ψ are separately determined and are compared to Colour Singlet NNLO⋆, Colour Evaporation Model, and FONLL predictions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
