The basic ideas and power counting rules of chiral perturbation theory are discussed. The formalism of velocity dependent fields for baryons, and for hadrons containing a heavy quark, is explained. UCSD/PTH 93-12 hep-ph/9305298 May 1993

We describe how isospin splitting and techniquark-technilepton splitting in one-family technicolor models can reduce the predicted value of the electroweak radiative correction parameter S, without making a large contribution to the T parameter.

The inclusive radiative B-decay is a sensitive probe of new physics, especially if related to the virtual exchange of a charged Higgs boson. Supersym-metric models provide a particularly interesting example. In the limit of exact supersymmetry, BR(b → sγ) = 0, due to the vanishing of any magnetic-moment transition operator. We illustrate the impact of this constraint for realistic values of the...

A slowly-running technicolor coupling will affect the size of non-oblique corrections to the Zb ¯ b vertex from extended technicolor dynamics. We show that while " walking technicolor " reduces the magnitude of the corrections, they generally remain large enough to be seen at LEP.
