Title: Theories of Flavor at the TeV scale.
Abstract: I will propose a class of theories to explain quark and lepton mass hierarchies where the scale of new physics can be at the TeV scale, without inducing the large flavor and CP violating processes that are often thought to relegate the origin of flavor to energies above 100 TeV. The models have new vector-like leptons and quarks, with mass mixings to each other and Yukawa couplings to light Standard Model fields encoded in chains reminiscent of dimensional deconstruction. A simple extension also generates neutrino masses, whose tiny size is parametrically related to the square of the electron Yukawa coupling. I will outline the essential features of these models, explain how fermion mass hierarchies and mixing angles emerge, and explore their phenomenological implications, testable both in the final run of the LHC as well as at possible future colliders.
