Description
The high luminosity and large cross section for b-quark production at the LHC makes possible the observation and study of many rare B meson decays. Recently, CMS reported on the presence of substructures in the known decay B+ → J/ψφK+. As part of that investigation, the final state B+ → ψ(2S)φK+ , with ψ(2S)→μ+μ− and φ → K+K− was also observed. We report the signal, with a significance of over 5 standard deviations using 19.6 fb-1 data collected at √s = 8 TeV at CMS, and its branching fraction measurement.
