Little Higgs theories often rely on an internal parity ("T- parity") to suppress nonstandard electroweak effects or to provide a dark matter candidate. We show that such a symmetry is generally broken by anomalies, as described by the Wess-Zumino-Witten term. We study a simple SU(3)×SU(3)/SU(3) Little Higgs scheme where we obtain a minimal form for the topological interactions of a single Higgs field. The results apply to more general models, including [SU(3)×SU(3)/SU(3)]4, SU(5)/SO(5), and SU(6)/Sp(6).
