摘要
Motivated by models of holographic technicolor, we discuss a four-site deconstructed Higgsless model with nontrivial wave function mixing. We compute the spectrum of the model, the electroweak triple gauge-boson vertices, and, for brane-localized fermions, the electroweak parameters to O(M(W)(2)/M(rho)(2)). We discuss the conditions under which alpha S vanishes (even for brane-localized fermions) and the (distinct but overlapping) conditions under which the phenomenologically interesting decay a(1)-> W gamma is nonzero and suppressed by only one power of (M(W)/M(rho)).
