Issue Date: | 2016 | Publisher: | Springer Nature | Serial title, monograph or event: | European Physical Journal C | Volume: | 76 | Issue: | 5 | Abstract: | The production rates of prompt and non-prompt J/ψ and ψ (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 √ s = 7 and 8 respectively. Production cross-sections for prompt as well as non-prompt sources, ratios of ψ (2S) to J/ψ production, and the fractions of nonprompt production for J/ψ and ψ (2S) are measured as a function of meson transverse momentum and rapidity. The measurements are compared to theoretical predictions. | URI: | https://hdl.handle.net/10316/108556 | DOI: | 10.1140/epjc/s10052-016-4050-8 | Rights: | openAccess |
