Measurement of CP observables in B± → DK± and B± → Dπ± with two- and four-body D decays
Measurements of CP observables in B± → D K ± and B± → Dπ± decays are presented where the D meson is reconstructed in the final states K ±π∓, π± K ∓, K + K −, π+π−, K ±π∓π+π−, π± K ∓π+π− and π+π−π+π−. This analysis uses a sample of charged B mesons from pp collisions collected by the LHCb experiment...
