R Symmetry Breaking Versus Supersymmetry Breaking
Ann E. Nelson, Nathan Seiberg
We point out a connection between R symmetry and \susy\ breaking. We show that the existence of an R symmetry is a necessary condition for \susy\ breaking and a spontaneously broke…
Cosmological Implications of Dynamical Supersymmetry Breaking
Tom Banks, David B. Kaplan, Ann E. Nelson
We provide a taxonomy of dynamical supersymmetry breaking theories, and discuss the cosmological implications of the various types of models. Models in which supersymmetry breaking…
Naturally Large Tan
Ann E. Nelson, Lisa Randall
We show that if there are only two Higgs doublets in the supersymmetric standard model, large requires a fine tuning in the parameters of the Lagrangian of order (…
Dynamical Supersymmetry Breaking at Low Energies
Michael Dine, Ann E. Nelson
Conventional approaches to supersymmetric model building suffer from several naturalness problems: they do not explain the large hierarchy between the weak scale and the Planck mas…
Progress in Electroweak Baryogenesis
A. G. Cohen, D. B. Kaplan, A. E. Nelson
Recent work on generating the excess of matter over antimatter in the early universe during the electroweak phase transition is reviewed.
