Maximal Abelian Flavor Symmetries
Juanca Carrasco-Martinez, Lawrence J. Hall
A framework, MAFS, is introduced that provides an approximate description of the hierarchies of quark and lepton masses and mixing angles in terms of a set of small parameters, $ε_…
Supersymmetric Framework for a Dynamical Fermion Mass Hierarchy
Nima Arkani-Hamed, Christopher D. Carone, Lawrence J. Hall +1
We propose a new framework for constructing supersymmetric theories of flavor, in which flavor symmetry breaking is triggered by the dynamical breakdown of supersymmetry at low ene…
Flavor Mixing Signals For Realistic Supersymmetric Unification
Nima Arkani-Hamed, Hsin-Chia Cheng, L. J. Hall
The gauge interactions of any supersymmetric extension of the standard model involve new flavor mixing matrices. The assumptions involved in the construction of minimal supersymmet…
Squark and Slepton Mass Relations in Grand Unified Theories
H. -C. Cheng, L. J. Hall
In the minimal supersymmetric standard model, assuming universal scalar masses at large energies, there are four intragenerational relations between the masses of the squarks and s…
Hypercharge and the Cosmological Baryon Asymmetry
Aram Antaramian, Lawrence J. Hall, Andrija Rašin
Stringent bounds on baryon and lepton number violating interactions have been derived from the requirement that such interactions, together with electroweak instantons, do not dest…
Operator Analysis For Oscillations
H. -C. Cheng, M. S. Gill, L. J. Hall
In grand unified theories the flavor mixing angles of leptons are related to those of quarks. In this paper we study SO(10) theories with a precise group theoretic relation at the…
