Event details

I introduce a new class of Composite Higgs models in which electroweak symmetry is broken by a seesaw-like mechanism. I present a specific realisation in which an SO(6) global symmetry is broken sequentially to SO(5), then to SO(4). The resulting Goldstone bosons lead to a composite two Higgs doublet model (2HDM) which can break electroweak symmetry without the need for the usual top quark loop corrections. I present some key results and discuss how the model eases many of the tensions related to the top partners -- the heavy fermionic bound states that are generic predictions of Composite Higgs models.

About Particle Physics Theory seminars

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
