Abstract
The prompt and non-prompt production cross-sections for ψ(2S) mesons are measured using 2.1 fb[superscript −1] of pp collision data at a centre-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. The measurement exploits the ψ(2S) → [J over ψ](→ μ[superscript +] μ[superscript −])π[superscript +] π[superscript −] decay mode, and probes ψ(2S) mesons with transverse momenta in the range 10 ≤ p[subscript T] < 100 GeV and rapidity |y| < 2.0. The results are compared to other measurements of ψ(2S) production at the LHC and to various theoretical models for prompt and non-prompt quarkonium production.
