Query: Fermion Sector of Little Higgs   The little Higgs mechanism provides an alternative solution to the hierarchy
problem, arguably fitting better into the phenomenological hint of the "little
hierarchy" which may cause some fine-tuning for the case of supersymmetry. We
discuss an aspect of little Higgs physics lacking proper attention -- the
construction of an interesting and consistent chiral fermionic sector and its
phenomenological implications. At least for the kind of example models to be
discussed, the gauge and top sector structure of a model largely dictates,
through gauge anomaly cancellation conditions, a specific chiral fermion
spectrum. The spectrum has interesting, family non-universal, flavor structure.
The implications for flavor physics are specially interesting. We also add a
brief comment of little Higgs versus supersymmetry.
