Determination of quantum numbers for several excited charmed mesons observed in $B^{-} \to D^{*+} π^{-} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +907

A four-body amplitude analysis of the $B^{-} \to D^{*+} π^{-} π^{-}$ decay is performed, where fractions and relative phases of the various resonances contributing to the decay are measu…
