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*[subscript 0](2400)0K⁻ , B⁻ →D*[subscript 2](2460)⁰K⁻ , and B⁻ →D*[subscript J](2760)0K⁻ decays, as well as from nonresonant sources. The D*[subscript J](2760)⁰ resonance is determined to have spin 1.
