Abstract
There is current interest in a possible new massive gauge boson which mixes slightly with the boson and accounts for certain anomalies in the LEP data. We show why constraints on models in which the boson does not couple to the first two families suggest dynamical electroweak symmetry breaking. The associated TeV mass fermions make up a fourth family. Constraints on the effects of the fourth left-handed neutrino also suggest a dynamical origin for its Majorana mass. We finally comment on related implications for the origin of quark masses.
