Abstract
A recent study by Randall and Sundrum shows that models of extended technicolor (ETC) have interesting implications on rare decays. We extend their study to the decay . The decay rate is found to be above the standard model prediction roughly by a factor of 4 in the case of "traditional" ETC models, and by a factor of order 30 for ETC models with a GIM mechanism. The current experimental bound is a factor of 5-15 above the standard model prediction, depending on the top-quark mass.
