Abstract
An analysis of the decays of and is presented in which the meson is reconstructed in the three-body final states , and . Using data from LHCb corresponding to an integrated luminosity of of collisions, measurements of several observables are performed. First observations are obtained of the suppressed Atwood-Dunietz-Soni decay and the quasi-Gronau-London-Wyler decay . The results are interpreted in the context of the unitarity triangle angle and related parameters.
