We summarize the indirect eects of new physics in a variety of processes. We consider precision electroweak measurements, the g 2 of the muon, rare decays, meson mixing, CP violation, lepton number violating interactions, double beta decay, and the electric dipole moments of atoms, molecules, and the neutron. We include discussions of both model independent(More)
Using precision electroweak data, we put limits on non-commuting extended technicolor models. We conclude that these models are viable only if the ETC-interactions are strong. Interestingly, these models predict a pattern of deviations from the standard model which can fit the data significantly better than the standard model does, even after taking into(More)
The triviality of the scalar sector of the standard one-doublet Higgs model implies that this model is only an effective low-energy theory valid below some cutoff scale Λ. The underlying high-energy theory must include flavor dynamics at a scale of order Λ or greater in order to give rise to the different Yukawa couplings of the Higgs to ordinary fermions.(More)
We explore corrections to electroweak parameters in the context of Extended Techni-color (ETC) models in which the ETC gauge-boson which generates the top-quark mass carries weak SU (2) charge. For m t ∼ 150 GeV there exist potentially large corrections to the Z decay width to b-quarks. Interestingly, in contrast to the situation in ETC models where the(More)
