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

Magnetic moments of the baryon decuplet in a relativistic quark model.

The magnetic moments of the baryon decuplet are calculated in a relativistic constituent quark model using the light-front formalism. Of particular interest are the magnetic moments of the Rand A +-Ifor which new recent experimental measurements are available. Our calculation for the magnetic moment ratio P@++)/P(P) is in excellent agreement with the experimental ratio, while our ratio I@>ldAO)...

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.
