A model-independent study of CP violation in B0->DK*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\,TeV. The CKM angle gamma is determined by examining the distributions of signal decays in phase-space bins of the self-conjugate D->KS0h+h- decays, where h=pi,K. Observables related to CP violation are measured and the angle gamma is determined to be gamma=(49-19+22)deg. Measurements of the amplitude ratio and strong-phase difference between the favoured and suppressed B0 decays are also presented.

Abstract

A model-independent study of CP violation in B0->DK*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\,TeV. The CKM angle gamma is determined by examining the distributions of signal decays in phase-space bins of the self-conjugate D->KS0h+h- decays, where h=pi,K. Observables related to CP violation are measured and the angle gamma is determined to be gamma=(49-19+22)deg. Measurements of the amplitude ratio and strong-phase difference between the favoured and suppressed B0 decays are also presented.
