| Popis: | 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(MW2/Mρ2). We discuss the conditions under which αS vanishes (even for brane-localized fermions) and the (distinct but overlapping) conditions under which the phenomenologically interesting decay a1→Wγ is nonzero and suppressed by only one power of (MW/Mρ). © 2008 The American Physical Society. |
