T-Parity Violation by Anomalies
Little Higgs theories often rely on an internal parity ("T-parity'') to
suppress non-standard 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) x 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) x SU(3)/SU(3)]^4, SU(5)/SO(5), and SU(6)/Sp(6).Comment: 17 page
Topcolor and the First Muon Collider (Talk presented at the Workshop on Physics at the First Muon Collider and at the Front End of the Muon Collider, Nov. 1997)
We describe a class of models of electroweak symmetry breaking that involves
strong dynamics and top quark condensation. A new scheme based upon a seesaw
mechanism appears particularly promising. Various implications for the
first-stage muon collider are discussed.Comment: 11 pages, no Fig
