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 VEVs of the bi--doublet βκ/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 Higgs boson. These may lead to observable lepton flavour violation effects including μ eγ decay with the rate close to its present experimental upper bound.
