Phenomenology of the Little Higgs model with X-Parity

In the popular littlest Higgs model, T-parity can be broken by Wess-Zumino-Witten (WZW) terms induced by a strongly coupled UV completion. On the other hand, certain models with multiple scalar multiplets (called moose models) permit the implementation of T-parity such that it is not broken by the WZW terms. Here we present a concrete realization of such a model, and discuss the phenomenology at the Large Hadron Collider, in particular differences with respect to the littlest Higgs model.
