High Energy Seminar -Kieran Holland (University of the Pacific) "Minimal Composite Higgs from new SU(3) gauge theory"

If the newly-discovered 126 GeV Higgs-like scalar is composite, breaking of Electroweak symmetry could be due to a new underlying gauge theory. I will discuss one such example: SU(3) gauge theory with 2 flavors of massless fermions in the 2-index symmetric ("sextet") representation. Especially important is whether or not a light composite scalar emerges after dynamical breaking of chiral symmetry. Our non-perturbative studies indicate this looks like a viable minimal model for BSM physics.
