The measurement exploits the ?(2S) ? J/?(? µ+µ-)p+p- decay mode, and probes ?(2S) mesons with transverse momenta in the range 10 = pT< 100 GeV and rapidity |y| < 2.0. The results are compared to other measurements of ?(2S) production at the LHC and to various theoretical models for prompt and non-prompt quarkonium production.
