Axions and a Gauged Peccei-Quinn Symmetry
Hsin-Chia Cheng, David Elazzar Kaplan
The axion solution to the strong CP problem requires an anomalous global U(1) symmetry. We show that the existence of such a symmetry is a natural consequence of an extra dimension…

Duality after Supersymmetry Breaking
Yael Shadmi, Hsin-Chia Cheng
Starting with two supersymmetric dual theories, we imagine adding a chiral perturbation that breaks supersymmetry dynamically. At low energy we then get two theories with soft supe…

Supersymmetric Lepton Flavor Violation at the NLC
Hsin-Chia Cheng
Supersymmetric theories generally have new flavor violation sources in the squark and slepton mass matrices. If significant lepton flavor violation exists, selectron and smuon shou…
