Abstract An analysis of B0DK0 decays is presented, where D represents an admixture of D0 and ¯D0 mesons reconstructed in four separate final states: Kπ+, πK+, K+K and π+π. The data sample corresponds to 3.0 fb1 of proton-proton collision, collected by the LHCb experiment. Measurements of several observables are performed, including CP asymmetries. The most precise determination is presented of rB(DK0), the magnitude of the ratio of the amplitudes of the decay B0DK+π with a bu or a bc transition, in a Kπ mass region of ±50 MeV/c2 around the K(892) mass and for an absolute value of the cosine of the K0 helicity angle larger than 0.4.
