Abstract: (arXiv)

We consider fermionic UV completions of little Higgs models and their associated T-parity-violating anomalous vertices. We show that the vacuum state of these models is unlikely to achieve the alignment necessary to realize anomaly-free coset theories. However, we will see that multi-link moose models posses an additional parity resulting in a novel phenomenology with long lived T-odd particles. Finally, we briefly discuss a method for identifying anomalous decays in colliders.
