Generic and Chiral Extensions of the Supersymmetric Standard Model
Hsin-Chia Cheng, Bogdan A. Dobrescu, Konstantin T. Matchev
We construct extensions of the Standard Model in which the gauge symmetries and supersymmetry prevent the dangerously large effects that may potentially be induced in a supersymmet…
A Chiral Supersymmetric Standard Model
Hsin-Chia Cheng, Bogdan A. Dobrescu, Konstantin T. Matchev
We propose a supersymmetric extension of the Standard Model with an extra U(1) gauge symmetry, so that all supersymmetric mass terms, including the -term, are forbidden by the g…
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…
Precision Supersymmetry Measurements at the e^-e^- Collider
Hsin-Chia Cheng
Measurements of supersymmetric particle couplings provide important verification of supersymmetry. If some of the superpartners are at the multi-TeV scale, they will escape direct…
Duality in the Presence of Supersymmetry Breaking
Hsin-Chia Cheng, Yael Shadmi
We study Seiberg duality for N=1 supersymmetric QCD with soft supersymmetry-breaking terms. We generate the soft terms through gauge mediation by coupling two theories related by S…
