Abstract

The rates of the rare flavor-changing processes, b → s γ and B_s → μ⁺ μ^- are estimated in extended technicolor models with and without a GIM mechanism. We find the b → s γ rate in ETC models with a GIM mechanism to be at most slightly larger than the standard model rate, whereas there is no significant extra model-independent contribution in other ETC scenarios. In the case of B_s → μ⁺ μ^-, ETC models with a GIM mechanism can yield a rate up to two orders of magnitude bigger than that of the standard model, whereas generic ETC scenarios are likely to give a rate which is about an order of magnitude bigger than that of the standard model.
