Measurement of CP violation parameters in B0 → DK*0 decays
An analysis of B 0 → D K * 0 decays is presented, where D represents an admixture of D 0 and ¯ D 0 mesons reconstructed in four separate final states: K − π + , π − K + , K + K − and π + π − . The data sample corresponds to 3.0 fb − 1 of proton-proton collision, collected by the LHCb experiment....

An analysis of B 0 → D K * 0 decays is presented, where D represents an admixture of D 0 and ¯ D 0 mesons reconstructed in four separate final states: K − π + , π − K + , K + K − and π + π − . The data sample corresponds to 3.0 fb − 1 of proton-proton collision, collected by the LHCb experiment. Measurements of several observables are performed, including C P asymmetries. The most precise determination is presented of r B ( D K * 0 ) , the magnitude of the ratio of the amplitudes of the decay B 0 → D K + π − with a b → u or a b → c transition, in a K π mass region of ± 50 MeV / c 2 around the K ∗ ( 892 ) mass and for an absolute value of the cosine of the K * 0 helicity angle larger than 0.4. |
