Abstract

The B^-→ D⁺K^-π^- decay is observed in a data sample corresponding to 3.0 fb^-1 of pp collision data recorded by the LHCb experiment during 2011 and 2012. Its branching fraction is measured to be B(B^-→ D⁺K^-π^-)=(7.31±0.19±0.22±0.39)×10^-5 where the uncertainties are statistical, systematic and from the branching fraction of the normalization channel B^-→ D⁺π^-π^-, respectively. An amplitude analysis of the resonant structure of the B^-→ D⁺K^-π^- decay is used to measure the contributions from quasi-two-body B^-→ D^∗₀(2400)⁰K^-, B^-→ D^∗₂(2460)⁰K^-, and B^-→ D^∗_J(2760)⁰K^- decays, as well as from nonresonant sources. The D^∗_J(2760)⁰ resonance is determined to have spin 1.
