Abstract
The resonant substructure of decays is studied with the Dalitz plot analysis technique. The study is based on a data sample corresponding to an integrated luminosity of of collision data recorded by LHCb. A structure at is found to be an admixture of spin-1 and spin-3 resonances. The masses and widths of these states and of the meson are measured, as are the complex amplitudes and fit fractions for all the and components included in the amplitude model. In addition, the resonance is confirmed to be spin 2.
