Abstract: We evaluate the sparticle mass spectrum in the minimal four-dimensionalconstruction that interpolates between gaugino and ordinary gauge mediation atthe weak scale. We find that even in the hybrid case - when the messengerscale is comparable to the mass of the additional gauge particles - both theright-handed as well as the left-handed sleptons are lighter than the bino inthe low-scale mediation regime. This implies a chain of lepton production and,consequently, striking signatures that may be probed at the LHC already in thenear future.
