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 m_3/2 \gtrsim 10 GeV. In a large domain of parameter space, the gravitino is the lightest superparticle with a scalar τ-lepton as the next-to-lightest superparticle.
