Recent topics on technicolor theory
Description
After a short historical review of technicolor theory and the so called FCNC problem, recent two models, asymptotically free (AF) and asymptotically nonfree (ANF) gauge theories are introduced to solve the FCNC problem. The relation is discussed between the two models by using the solutions of improved planar Schwinger-Dyson equation. We observe two types of the ultraviolet fixed points, the one corresponds to the so-called trivial ultraviolet fixed point usually observed in AF gauge theories, and the other to the nontrivial ultraviolet fixed point. In the last part of this paper I would like to make a comment on the essence of FCNC problem comes from the momentum dependence of the dynamical generated fermion mass function. (author)
