Recent experimental discoveries encourage speculation that there may be more than four “flavors” of tricolored quarks and/or new flavors of leptons. A vectorlike gauge theory of the weak, electromagnetic, and associated neutral current interactions is then an attractive possibility. We present as an illustrative example a minimal theory based on six quark flavors and six lepton flavors and on the group SU2 × U1 (presumably a subgroup of a larger gauge group).
