Measurement of the CKM angle γ in the B0 → DK[ast]0 channel using self-conjugate D→K0Sh+h- decays

A model-independent study of CP violation in B0 → DK*0 decays is presented using data corresponding to an integrated luminosity of 9fb-1 collected by the LHCb experiment at centre-of-mass energies of √s=7, 8 and 13 TeV. The CKM angle γ is determined by examining the distributions of signal decays in...

Description
Summary:A model-independent study of CP violation in B0 → DK*0 decays is presented using data corresponding to an integrated luminosity of 9fb-1 collected by the LHCb experiment at centre-of-mass energies of √s=7, 8 and 13 TeV. The CKM angle γ is determined by examining the distributions of signal decays in phase-space bins of the self-conjugate D → K0S h+h- decays, where h = π, K. Observables related to CP violation are measured and the angle γ is determined to be γ = 49 + 22 -̊. Measurements of the amplitude ratio and strong-phase difference between the favoured and suppressed B 0 decays are also presented.
