Anomalous Flavor U(1)_X for Everything
Herbi K. Dreiner, Hitoshi Murayama, Marc Thormeier
We present an ambitious model of flavor, based on an anomalous U(1)_X gauge symmetry with one flavon, only two right-handed neutrinos and only two mass scales: M_{grav} and m_{3/2}…
Supersymmetric Froggatt-Nielsen Models with Baryon- and Lepton-Number Violation
Herbi K. Dreiner, Marc Thormeier
We systematically investigate the embedding of U(1)_X Froggatt-Nielsen models in (four-dimensional) local supersymmetry. We restrict ourselves to models with a single flavon field.…
Supernovae and Light Neutralinos: SN1987A Bounds on Supersymmetry Revisited
H. K. Dreiner, C. Hanhart, U. Langenfeld +1
For non-universal gaugino masses, collider experiments do not provide any lower bound on the mass of the lightest neutralino. We review the supersymmetric parameter space which lea…
