Abstract

We discuss the proper starting point for looking into flavor physics from the perspective of solving the hierarchy problem with the little Higgs mechanism - the construction of anomaly-free fermionic spectra of the effective theory of extended electroweak gauge symmetry around the TeV scale. Anomaly cancellations among the three SM families, plus extra fermions, are typically needed, giving family non-universal flavor structures. Such a completed and consistent fermionic spectrum supplements a scalar-sector little Higgs model, turning the latter into a realistic model, the phenomenological viability of which can then be investigated. The implications for flavor physics are specially interesting. We give further elaborated discussion here on our basic perspective, trying to clarify issues that are in our opinion under-appreciated. We also add a brief comment on little Higgs versus supersymmetry.
