Resum

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 π±π0, π+π-π0 and K+K-π0. Using data from LHCb corresponding to an integrated luminosity of 3.0fb-1 of pp collisions, measurements of several CP observables are performed. First observations are obtained of the suppressed Atwood-Dunietz-Soni decay B → [π K± π0]Dπ and the quasi-Gronau-London-Wyler decay B → [K+ K- π0]Dπ. The results are interpreted in the context of the unitarity triangle angle γ and related parameters.
