A New Model of Topcolor-Assisted Technicolor

I present a model of topcolor-assisted technicolor that can have topcolor breaking of the desired pattern, hard masses for all quarks and leptons, mixing among the heavy and light generations, and explicit breaking of all technifermion chiral symmetries except electroweak $SU(2)\otimes$U(1). These positive features depend on the outcome of vacuum alignment. The main flaw in this model is tau-lepton condensation.
