Abstract
Measurements of CP observables in B →DK 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 in 2011 and 2012, corresponding to an integrated luminosity of 3.0 fb . Various CP-violating effects are reported and together these measurements provide important input for the determination of the unitarity triangle angle γ. The analysis of the four-pion D decay mode is the first of its kind. ± ± ± ± ± ∓ ± ∓ + − + − ± ∓ + − ± ∓ + − + − + − −1
