Abstract

Parity violation in the left-right-symmetric gauge model is naturally understood in a composite model by imposing the consistency of the model, that is, stability of the Higgs potential and positivity of squared masses of observable mesons. Two quite different types of solutions, which are respectively characterized with massless neutrinos and nonzero-mass neutrinos, are left as realistic solutions and the choice of one of them is determined by the sign of one coupling constant in the Higgs potential. The model predicts some Higgs mesons with masses of the order of $M_{W_{L}}$ (∼100 GeV), one of which will be observed in the charged lepton-antilepton pair decays, such as the $τ^{-}$ $τ^{+}$ mode.

We can introduce a scalar preon $S_{8}$ with the representation of (8, 1, 2, 2, $N_{B - L}$ =0) of the gauge group G. We can introduce Yukawa couplings like g ${sum}_{a = l, q}$ { $t_{R}^{a}}$ bar $S_{8}$ $t_{L}^{a}$ +H.c. without any change in the discussion given in Ref. 1.
