Observation of the decay B+ ? ?(2S)?(1020)K+ in pp collisions at s=8TeV

Abstract: The decay B+??(2S)?(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+??(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.
