摘要
We present a one-doublet extended technicolor model, with all fermions in fundamental representations. The bare Lagrangian has no explicit mass terms but generates masses through gauge symmetry breaking by purely QCD-like dynamics. The model generates three families of quarks and leptons and can accommodate the observed third family mass spectrum (including a large top quark mass and light neutrinos). In addition, we show how the model may be extended to incorporate a top color driven top quark mass without the need for a strong U(1) interaction. We discuss the compatibility of the model with experimental constraints and its possible predicitive power with respect to first and second family masses.
