abstract: 'We discuss the deconstructed version of a topcolor-assisted technicolor model wherein the mechanism of top quark mass generation is separated from the rest of electroweak symmetry breaking. The minimal deconstructed version of this scenario is a “triangle moose” model, where the top quark gets its mass from coupling to a top-Higgs field, while the gauge boson masses are generated from a Higgsless sector. The spectrum of the model includes scalar (top-Higgs) and pseudoscalar (top-pion) states. In this paper, we study the properties of these particles, discuss their production mechanisms and decay modes, and suggest how best to search for them at the LHC.'

Introduction
============

Higgsless models, as the name implies, break the electroweak symmetry without invoking a fundamental scalar particle. Inspired by the idea that one could maintain perturbative unitarity in extra-dimensional models through heavy vector resonance exchanges in lieu of a Higgs [@SekharChivukula:2001hz; @Chivukula:2002ej; @Chivukula:2003kq], Higgsless models were intially introduced in an extra-dimensional context as $SU(2)\times SU(2)\times U(1)$ gauge theories living in a slice of
