Abstract

An analysis of the decays of B∓ → DK∓ and B∓ → Dπ∓ is presented in which the D meson is reconstructed in the three-body final states K∓ππ0, πþπ−π0 and KþK−π0. Using data from LHCb corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions, measurements of several CP observables are performed. First observations are obtained of the suppressed Atwood-Dunietz-Soni decay B∓ → ½π∓Kπ0Dπ∓ and the quasi-Gronau-London-Wyler decay B∓ → ½KþK−π0Dπ∓. The results are interpreted in the context of the unitarity triangle angle γ and related parameters.
