Spontaneously Broken Technicolor and the Dynamics of Virtual Vector Technimesons
Christopher T. Hill, Dallas C. Kennedy, Tetsuya Onogi, Hoi--Lai Yu
Abstract
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 techni--gluon 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.
