Abstract

An analysis of B ^± → DK ^± and B ^± → Dπ ^± decays is presented where the D meson is reconstructed in the four ^-body nal state K ^±π ^∓π ⁺π-. Using LHCb data corresponding to an integrated luminosity of 1.0 fb ^-1, rst observations are made of the suppressed ADS modes B ^± →[π ^±K ^∓π ⁺π-] D K ^± and B ^± → [π ^±K ^∓π ⁺π-]Dπ ^± with a signicance of 5.1σ and greater than 10σ, respectively. Measurements of CP asymmetries and CP ^-conserving ratios of partial widths from this family of decays are also performed. The magnitude of the ratio between the suppressed and favoured B ^± → DK ^± amplitudes is determined to be r ^K _B = 0.097±0.011.
