Flavour from accidental symmetries
We consider a new approach to fermion masses and mixings in which no special “horizontal” dynamics is invoked to account for the hierarchical pattern of charged fermion masses and for the peculiar features of neutrino masses. The hierarchy follows from the vertical, family-independent structure of the model, in particular from the breaking pattern of the Pati-Salam group. The lightness of the f...
متن کاملMass hierarchy and flavour mixing from discrete symmetries
are fully compatible with the so-called Tri-Bimaximal (TB) mixing pattern which corresponds to a maximal θ23, an zero θ13 and a “magic” value of solar angle: sin 2 θ12 = 1/3. It is well known that the lepton mixing angles can be understood by a mechanism of vacuum misalignment in flavour space occurring in theories with non-abelian flavour symmetries [2]. Also the charged lepton mass hierarchy ...
متن کاملFamily symmetries and the SUSY flavour problem
We re-examine the constraints on continuous family symmetries coming from flavour changing neutral current limits on the D−term contributions to squark and slepton masses. We show that, for a restricted choice of the familon sector, continuous family symmetries are consistent with even the most conservative limits both for the case of gauge mediated supersymmetry breaking and the case of gravit...
متن کاملModels of flavour with discrete symmetries
We briefly review some recent developments in theoretical models of fermion masses, mixings and CP violation with discrete non-Abelian symmetries. Then, we explain the main ideas of a recently proposed Minimal S3−invariant Extension of the Standard Model and its application to a unified analysis of masses, mixings and CP violation in the leptonic and quark sectors as well as the explicit comput...
متن کاملApproximate Flavour Symmetries and See-Saw Mechanism
We study the approximate flavour symmetries imposed on the lepton sector assuming see-saw mechanism as the neutrino mass structure. We apply the symmetry to various neutrino phenomenologies and obtain constraints on neutrino masses and mixings. Typeset using REVTEX [email protected] 1
