چکیده
Requiring that the baryon number of the universe be generated by anomalous elec-troweak interactions places strong constraints on the minimal supersymmetric standard model. In particular, the electric dipole moment of the neutron must be greater than 10 −27 e-cm. Improvement of the current experimental bound on the neutron's electric dipole moment by one order of magnitude would constrain the lightest chargino to be lighter than 88 GeV, and the the lightest neutralino to be lighter than 44 GeV. In extensions of this model with gauge singlet superfields all of these bounds are eliminated.

Heavy Meson Hyperfine Splittings: A Puzzle for Heavy Quark Chiral Perturbation Theory
We show that there is a large discrepancy between the expected light flavor dependence of the heavy pseudoscalar–vector mass splittings and the measured values. We demonstrate that the one–loop calculation is unreliable. Moreover, agreement with experiment requires the leading dependence on SU(3) symmetry breaking to be nearly cancelled, so that the heavy quark mass dependence is unknown and th...
متن کاملComposite Intermediary and Mediator Models of Gauge-Mediated Supersymmetry Breaking
We discuss gauge-mediated models which employ a tree-level mass term in the superpotential. We give explicit composite realizations in which the mass terms are not fundamental. Instead, they arise as effective terms in the superpotential from confining gauge dynamics. Work supported in part by the US Department of Energy under cooperative agreement #DE-FC0294ER40818. Address after August 1: Dep...
متن کاملConstraints on a massive Dirac neutrino model.
We examine constraints on a simple neutrino model in which there are three massless and three massive Dirac neutrinos and in which the left handed neutrinos are linear combinations of doublet and singlet neutrinos. We examine constraints from direct decays into heavy neutrinos, indirect effects on electroweak parameters, and flavor changing processes. We combine these constraints to examine the...
متن کامل1 Ju n 19 92 A Method for Simulating Chiral Fermions on the Lattice
I show that a lattice theory of massive interacting fermions in 2n + 1 dimensions may be used to simulate the behaviour of massless chiral fermions in 2n dimensions if the fermion mass has a step function shape in the extra dimension. The massless states arise as zeromodes bound to the mass defect, and all doublers can be given large gauge invariant masses. The manner in which the anomalies are...
متن کاملDestabilizing Divergences in Supergravity Theories at Two Loops
We examine the stability of the mass hierarchy in hidden-sector supergravity theories. We show that a quadratically divergent tadpole can appear at two loops, even in minimal supergravity theories, provided the theory has a gaugeand global-symmetry singlet with renormalizable couplings to the visible fields. This tadpole can destabilize the hierarchy. We also find a quadratically divergent two-...
متن کاملLow-Energy Kähler Potentials In Supersymmetric Gauge Theories With (Almost) Flat Directions
We derive the supersymmetric low-energy effective theory of the D-flat directions of a supersymmetric gauge theory. The Kähler potential of Affleck, Dine and Seiberg is derived by applying holomorphic constraints which manifestly maintain supersymmetry. We also present a simple procedure for calculating all derivatives of the Kähler potential at points on the flat direction manifold. Together w...
