Abstract: (Springer)
The production rates of prompt and non-prompt J/ψJ/\psi and ψ(2S)\psi (2\mathrm {S}) mesons in their dimuon decay modes are measured using 2.1 and 11.4 fb1^{-1} of data collected with the ATLAS experiment at the Large Hadron Collider, in proton–proton collisions at s=7\sqrt{s}=7 and 8 respectively. Production cross-sections for prompt as well as non-prompt sources, ratios of ψ(2S)\psi (2\mathrm {S}) to J/ψJ/\psi production, and the fractions of non-prompt production for J/ψJ/\psi and ψ(2S)\psi (2\mathrm {S}) are measured as a function of meson transverse momentum and rapidity. The measurements are compared to theoretical predictions.
