The Three Families from SM-like Chiral Models
We give a detailed description of the model construction procedures about our
new approach to the family structure of the standard model. SM-like chiral
fermion spectra, largely "derivable" from the gauge anomaly constraints, are
formulated in a symmetry
framework as an extension of the SM symmetry. The case gives naturally
three families as a result, with nontrivially embedded into the
. Such a spectrum has extra vector-like quarks and
leptons. We illustrate how an acceptable symmetry breaking pattern can be
obtained through a relatively simple scalar sector which gives naturally
hierarchical quark mass matrices. Compatibility with various FCNC constraints
and some interesting aspects of the possible phenomenological features are
discussed, from a non-model specific perspective. The question of incorporating
supersymmetry without putting in the Higgses as extra supermultiplet is also
addressed.Comment: 43 pages RevTex, including 9 tables and 3 figure
