摘要：
In view of both the latest LHCb measurement of R-K(*) and the new 2.7 sigma deviation reported by Belle II on B+ -> K+nu(nu) over bar decays, we present a fit to the B meson anomalies for various one and two dimensional hypothesis including complex Wilson coefficients. We show in a model-independent way that the generic non-universal U(1)' extensions of the SM, without flavour violation, fail to simultaneously fit those observables and corroborate that, they can modify BR(B+-> K+nu(nu) over bar )up to only a 10%. In view of this deficit, we propose a new way in which those models can accommodate the data at tree level by introducing lepton flavour violating couplings and non-diagonal elements of the charged lepton mixing matrix, with implications in future charged lepton flavour violation searches.
