Abstract

The decay B+→ψ(2S)ϕ(1020)K+ is observed for the first time using data collected from pp collisions at sqrt(s)=8 TeV source by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb-1 source. The branching fraction of this decay is measured, using the mode B+→ψ(2S)K+ as normalization, to be 4.0 +- 0.4 stat +- 0.6 sys+- 0.2, where the third uncertainty is from the measured branching fraction of the normalization channel.
