Spontaneous CP-violation in extended technicolor models
The spontaneous CP-violation in models with dynamically broken weak interaction symmetries, i.e., extended technicolor models is examined. Attention is focussed on situations in which the global, flavor symmetry of the strong, color-technicolor, interactions is a product of chiral, horizontal U(2), or, when weak degrees of freedom are included, U(4) factors. In this context, we demonstrate the Eichten, Lane, Preskill CP-violation mechanism and show that the nemesis of this mechanism, strong CP-violation, can be easily avoided by imposing a discrete symmetry on the chiral perturbation. When strong CP-invariance is preserved by this means, we find that spontaneously generated CP-violating phases are suppressed by a ratio of extended technicolor mass scales. In addition, we consider, and attempt to analyze the direct contribution to strong CP-violation from colored technifermions.
