摘要：

We propose spontaneously breaking technicolor, thus liberating techniquarks and suppressing large resonance contributions to the electroweak S parameter. The dynamics is modeled by a fermion bubble approximation to a single massive technigluon exchange potential. This contains a Nambu-Jona-Lasinio model with additional interactions. ''Virtual'' vector mesons occur and contribute to S, and their effects are studied. Models of broken technicolor are discussed.
