Abstract

The decay B- ⁰ _s→ ψ(2S)K ⁺π ^-is observed using a data set corresponding to an integrated luminosity of 3.0fb ^-1collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. The branching fraction relative to the B ⁰→ ψ(2S)K ⁺π ^-decay mode is measured to be, where fs/fd indicates the uncertainty due to the ratio of probabilities for a b quark to hadronise into a B ⁰ _sor B ⁰meson. Using an amplitude analysis, the fraction of decays proceeding via an intermediate K*(892) ⁰meson is measured to be 0.645±0.049(stat)±0.049(syst) and its longitudinal polarisation fraction is 0.524±0.056(stat)±0.029(syst). The relative branching fraction for this component is determined to be. In addition, the mass splitting between the B ⁰ _sand B ⁰mesons is measured as M(B ⁰ _s)-M(B ⁰)=87.45±0.44(stat)±0.09(syst)MeV/c ².
