Abstract: Different theoretical and phenomenological aspects of the Minimal andNonminimal Walking Technicolor theories have recently been studied. The goalhere is to make the models ready for collider phenomenology. We do this byconstructing the low energy effective theory containing scalars, pseudoscalars,vector mesons and other fields predicted by the minimal walking theory. Weconstruct their self-interactions and interactions with standard model fields.Using the Weinberg sum rules, opportunely modified to take into account thewalking behavior of the underlying gauge theory, we find interesting relationsfor the spin-one spectrum. We derive the electroweak parameters using the newlyconstructed effective theory and compare the results with the underlying gaugetheory. Our analysis is sufficiently general such that the resulting model canbe used to represent a generic walking technicolor theory not at odds withprecision data.
