| Summary: | An analysis of the decays of B[superscript ∓] → DK[superscript ∓] and B[superscript ∓] → Dπ[superscript ∓] is presented in which the D meson is reconstructed in the three-body final states K[superscript ∓]π[superscript ±]π[superscript 0], π[superscript +]π[superscript −]π[superscript 0] and K[superscript +]K[superscript −]π[superscript 0]. Using data from LHCb corresponding to an integrated luminosity of 3.0 fb[superscript −1] of pp collisions, measurements of several CP observables are performed. First observations are obtained of the suppressed Atwood-Dunietz-Soni decay B[superscript ∓] → [π[superscript ∓]K[superscript ±]π[superscript 0]][subscript D]π[superscript ∓] and the quasi-Gronau-London-Wyler decay B[superscript ∓] → [K[superscript +]K[superscript −]π[superscript 0]][subscript D]π[superscript ∓]. The results are interpreted in the context of the unitarity triangle angle γ and related parameters. |
