Abstract

The decay B⁺→ψ(2S)ϕ(1020)K⁺ is observed for the first time using data collected from pp collisions at s=8TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6fb⁻¹. 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(syst)±0.2(B))×10⁻⁶, where the third uncertainty is from the measured branching fraction of the normalization channel.
