Abstract
An analysis of B[superscript 0]→DK[superscript ∗0] decays is presented, where D represents an admixture of D[superscript 0] and [bar over D][superscript 0] mesons reconstructed in four separate final states: K[superscript -]π[superscript +], π[superscript -]K[superscript +], K[superscript +]K[superscript -] and π[superscript +]π[superscript -]. The data sample corresponds to 3.0fb[superscript -1] 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 r[subscript B](DK[superscript ∗0]), the magnitude of the ratio of the amplitudes of the decay B[superscript 0]→DK[superscript +]π[superscript -] with a b→u or a b→c transition, in a Kπ mass region of ±50 MeV/c[superscript 2] around the K∗(892) mass and for an absolute value of the cosine of the K[superscript ∗0] helicity angle larger than 0.4.
