Abstract
We present a composite scenario based on the $\mathrm{S}{\mathrm{U}}_{L}(2)\ensuremath{\bigotimes}\mathrm{U}{(1)}_{Y}\ensuremath{\bigotimes}\mathrm{S}{\mathrm{U}}_{L}^{*}(2)$ group. New interactions are predicted at the usual electroweak scale. New heavy fermions can be produced in a renormalizable model. A new type of light excited neutrinos can occur and are shown to be naturally consistent with the recent results from the CERN ${e}^{+}{e}^{\ensuremath{-}}$ collider LEP on the $Z$ width.
