Flavor universal dynamical electroweak symmetry breaking - art. no. 115005

The top condensate seesaw mechanism of Dobrescu and Hill allows electroweak symmetry to be broken while deferring the problem of flavor to an electrow eak singlet, massive sector. We provide an extended version of the singlet sector that naturally accommodates realistic masses for all the standard mo del fermions, which play an equal role in breaking electroweak symmetry. Th e models result in a relatively light composite Higgs sector with masses ty pically in the range of (400-700) GeV. In more complete models the dynamics will presumably be driven by a broken gauged family or flavor symmetry gro up. As an example of the higher scale dynamics a fully dynamical model of t he quark sector with a GIM mechanism is presented, based on an earlier top condensation model of King using broken family gauge symmetry interactions (that model was itself based on a technicolor model of Georgi). The crucial extra ingredient is a reinterpretation of the condensates that form when s everal gauge groups become strong close to the same scale. A related techni color model of Randall which naturally includes the leptons too may also be adapted to this scenario. We discuss the low energy constraints on the mas sive gauge bosons and scalars of these models as well as their phenomenolog y at the TeV scale. [S0556-2821(99)07609-2].
