Title: Dynamical left-right symmetry breaking

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{close_quote}s of the bidoublet tan{beta}{equivalent_to}{kappa}/{kappa}{sup {prime}}{approx_equal}1.3{endash}4. For a theoretically plausible choice of the parameters the right-handed scale can be as low as {approximately}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 {mu}{r_arrow}{ital e}{gamma} decay with the rate close to its present experimental upper bound. {copyright} {ital 1996 The American Physical Society.}
