The production rates of prompt and non-prompt J/? and ?(2S) mesons in their dimuon decay modes are measured using 2.1 and 11.4 fb -¹ of data collected with the ATLAS experiment at the Large Hadron Collider, in proton–proton collisions at vs = 7 and 8 respectively. Production cross-sections for prompt as well as non-prompt sources, ratios of ?(2S) to J/? production, and the fractions of non-prompt production for J/? and ?(2S) are measured as a function of meson transverse momentum and rapidity. The measurements are compared to theoretical predictions.
