Squarks and Sleptons between Branes and Bulk — •Kai Schmidt-Hoberg, Wilfried Buchmueller, and Joern Kersten — DESY Theory Group, 22603 Hamburg, Germany

We study gaugino-mediated supersymmetry breaking in a six-dimensional SO(10) orbifold GUT model where quarks and leptons are mixtures of brane and bulk fields. The couplings of bulk matter fields to the supersymmetry breaking brane field have to be suppressed in order to avoid large FCNCs. We derive bounds on the soft supersymmetry breaking parameters and calculate the superparticle mass spectrum.
