A High-Quality Axion from Exact SUSY Chiral Dynamics
T. Gherghetta, H. Murayama, B. Noether +1
We use supersymmetric chiral dynamics perturbed by anomaly-mediated supersymmetry breaking to obtain a high-quality, composite axion that solves the strong CP problem. The strong d…
Strong CP and Flavor in Multi-Higgs Theories
Lawrence Hall, Claudio Andrea Manzari, Bea Noether
We introduce a class of multi-Higgs doublet extensions of the Standard Model that solves the strong CP problem with profound consequences for the flavor sector. The Yukawa matrices…
Observing Leptogenesis in Action with Gravitational Waves
Hitoshi Murayama, Bea Noether, Jan Schütte-Engel
Leptogenesis is arguably the best motivated theory of baryogenesis given the discovery of finite neutrino masses, yet its experimental test is elusive given its high energy scale.…
Two Higgs Doublet Solutions to the Strong CP Problem
Quentin Bonnefoy, Lawrence J. Hall, Claudio Andrea Manzari +1
We solve the strong CP problem in a broad class of two Higgs doublet theories that will be probed at the Large Hadron Collider and at future colliders. These theories feature CP an…
