A High-Quality Axion from Exact SUSY Chiral Dynamics Open
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 dynamics arises from a supersymmetric SU(10) chiral gauge th…

Two Higgs Doublet Solutions to the Strong CP Problem Open
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 and Abelian flavor symmetries, both broken softly in the scal…

Strong CP and Flavor in Multi-Higgs Theories Open
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 are constrained to have many zero entries by a "Higgs-Flav…

Guide to anomaly-mediated supersymmetry-breaking QCD Open
We present a careful study of the chiral symmetry breaking minima and the baryonic directions in supersymmetric QCD ($SU (N_c)$ with $N_f$ flavors) perturbed by anomaly mediated supersymmetry breaking (AMSB). For the s-confining case of $N…

A Guide to AMSB QCD Open
We present a careful study of the chiral symmetry breaking minima and the baryonic directions in supersymmetric QCD ($SU(N_c)$ with $N_f$ flavors) perturbed by Anomaly Mediated Supersymmetry Breaking (AMSB). For the s-confining case of $N_…

Broken Conformal Window Open
We show that near the edges of the conformal window of supersymmetric $SU(N_c)$ QCD, perturbed by Anomaly Mediated Supersymmetry Breaking (AMSB), chiral symmetry can be broken depending on the initial conditions of the RG flow. We do so by…

Non-perturbative Effects and Unparticle Physics in Generalized Schwinger Models Open
We analyze generalizations of the Schwinger model with more massless fermions and more vector fields. We focus on models with the gauge structure of ``diagonal color $SU(n)$'' but unlike previous investigators, we do not assume that all th…
