Not T-parity but C-parity
arXiv:0801.0344
Abstract
We revisit the Littlest Higgs model with -parity, and discover a symmetry on collective symmetry. It is dubbed collective parity ($\EuScript{C}$-parity). We demonstrate that -parity is consistent with $\EuScript{C}$-parity. We further investigate the origin of the collective symmetry in the context of composite Higgs and find a new path to the UV complete theory of the model. In addition, we demonstrate that -parity violating processes naturally take place.
