TITLE Frugal ?(1)? models with non-minimal flavor violation for ?→?ℓℓ anomalies and neutrino mixings
ABSTRACT We present a class of ?(1)? models which are can simultaneously explain the neutrino mixings and flavor anomalies in neutral B decays. The frugal set up apart from additional ?′, requires additional singlet scalar for neutrino mixings and an additional scalar doublet for quark mixings. Our set up identifies a class of symmetries wherein all generations of quarks are necessarily charged, rendering collider constraints to be stringent. We show all our models with the assumption of CKM-like mixings are ruled out from the current data. Introduction of a single source parameter for non-minimal mixings allows for a wider class of models consistent with the data. We show the viable symmetry patterns are of the form ???3?????, ???3??+??, and ??+3?????.
