| Abstract: | A model-independent study of C P violation in B 0 → D K ∗ 0 decays is presented using data corresponding to an integrated luminosity of 9 \,fb - 1 collected by the LHCb experiment at centre-of-mass energies of s = 7 , 8 and 13 \,Te V . The CKM angle γ is determined by examining the distributions of signal decays in phase-space bins of the self-conjugate D → K S 0 h + h - decays, where h = π , K . Observables related to C P violation are measured and the angle γ is determined to be γ = (49 - 19 + 22) ∘ . Measurements of the amplitude ratio and strong-phase difference between the favoured and suppressed B 0 decays are also presented. [ABSTRACT FROM AUTHOR] |
