Phenomenology of the top mass in realistic extended technicolor models

Extended technicolor contribution to the Zbb vertex.

The diagonal contribution can naturally explain the LEP result of Rb in some models of the ETC theory and some mechanisms which genera~e negative contribution to the T parameter are needed to explain the the experimental value of R b by the diagonal ETC boson.

Chiral-symmetry breaking in asymptotically free theories with slowly running couplings is analyzed and an enhancement of the fermion condensate defined with the ultraviolet cutoff M, while the Goldstone-boson decay constant F remains essentially unaltered.

Nonoblique effects in the Zbb-bar vertex from extended technicolor dynamics.

Extended technicolor theories generate potentially large corrections to the {ital Zb{bar b}} vertex which can be observed in current experiments at the CERN {ital e}{sup +}{ital e{minus}} collider…
