Ann E. Nelson

University of Washington
Mathematical and Physical Sciences
Model builder whose work has had considerable influence on the phenomenology of particle physics and on cosmology. Topics include CP violation, baryogenesis, neutrino oscillations, dense nuclear matter, and dark matter. Had particular impact on attempts to understand why the electroweak symmetry breaking scale is so much smaller than the Planck scale. Work with Dine on dynamical supersymmetry breaking at low energy opened up a new area of model building in supersymmetric extensions of the Standard Model. Nelson's subsequent contributions to the topic continue to be influential. She also made contributions to the Little Higgs scenario, an alternative approach to understanding the electroweak scale.
