New Multi-Scale Supersymmetric Models with Flavor Changing Neutral Current Suppression
Sandro Ambrosanio, Ann E. Nelson
We discuss the phenomenology of a class of supersymmetric models in which some of the quark and lepton superfields are an integral part of a dynamical supersymmetry breaking sector…
Counting 4 pi 's in Strongly Coupled Supersymmetry
Andrew G. Cohen, David B. Kaplan, Ann E. Nelson
We extend the "naive dimensional analysis" arguments used in QCD for estimating the strengths of operators in chiral Lagrangians to strongly coupled supersymmetric theories. In par…
CP Violation and FCNC in the Third Family from Effective Supersymmetry
Ann E. Nelson
I discuss a ``more minimal'' modification of the minimal supersymmetric standard model, in which supersymmetry breaking is connected with the physics of flavor. Flavor Changing Neu…
Contact Terms, Compositeness, and Atomic Parity Violation
Ann E. Nelson
The most severe constraints on quark-lepton four-fermion contact interactions come from the agreement of atomic parity violation measurements with the Standard Model. In this lette…
Horizontal, Anomalous U(1) Symmetry for the More Minimal Supersymmetric Standard Model
Ann E. Nelson, David Wright
We construct explicit examples with a horizontal, ``anomalous'' gauge group, which, in a supersymmetric extension of the standard model, reproduce qualitative features of th…
