Measurement of the CKM angle γ in the B0→D K∗0 channel using self-conjugate D →KS0h+h- decays
Abstract
A model-independent study of C P violation in B0→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 TeV . The CKM angle γ is determined by examining the distributions of signal decays in phase-space bins of the self-conjugate D →KS0h+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 B0 decays are also presented.
