A Gauge-Mediation Model of Dynamical SUSY Breaking with a Wide Range of the Gravitino Mass
Abstract
We provide a gauge-mediation model of dynamical supersymmetry breaking where the gravitino mass takes a value in a wide range from 0.1 eV to 10 GeV. The lower mass region of order 100 keV or less deserves experimental and cosmological interests. The vacuum of our model is a true one without runaway instability, which may be desirable in a cosmological evolution of the universe.
