Abstract
We study a left-right symmetric model which contains only elementary gauge boson and fermion fields and no scalars. The phenomenologically required symmetry breaking emerges dynamically leading to a composite Higgs sector with a renormalizable effective Lagrangian. We discuss the pattern of symmetry breaking and phenomenological consequences of this scenario. It is shown that a viable top quark mass can be achieved for the ratio of the VEV’s of the bidoublet tanβ≡κ/≃1.3–4. For a theoretically plausible choice of the parameters the right-handed scale can be as low as ∼20 TeV; in this case one expects several intermediate and low-scale scalars in addition to the standard model Higgs boson. These may lead to observable lepton flavor violation effects including μ→eγ decay with the rate close to its present experimental upper bound. © 1996 The American Physical Society.
