A Completed Chiral Fermionic Sector Model with Little Higgs

Abstract

The Standard Model has some intrinsic beauty in the sector of fermions and gauge bosons. Its scalar sector, though minimal, is however haunted by the hierarchy problem. The fermionic spectrum also have two major problems, the flavor problem with its fundamental notion about why there are three families, and the phenomenological limitation of massless neutrinos. We present here a completed chiral fermionic sector model, based on a little Higgs model, that has the plausible potential of addressing all these problems of the SM at an accessible energy scale, and comment briefly on its phenomenology. The focus here is not on the little Higgs part, but rather on the electroweak quarks and leptons from the model, which of course from an important part of the full model.
