The Gravitino in Gaugino Mediation
arXiv:hep-ph/0506105 · doi:10.1016/j.physletb.2005.11.003
Abstract
We show that for gaugino mediated supersymmetry breaking the gravitino mass is bounded from below. For a size of the compact dimensions of order the unification scale and a cutoff given by the higher-dimensional Planck mass, we find . In a large domain of parameter space, the gravitino is the lightest superparticle with a scalar -lepton as the next-to-lightest superparticle.
