Abstract

We propose a new framework of low-scale gauge-mediated supersymmetry (SUSY) breaking with a gravitino mass of O(100) TeV. The usual 4D gauge mediation models predict a light gravitino and suffer from cosmological problems. In our framework, a heavy gravitino in gauge mediation is realized with a flat extra dimension, whose compactification scale is around the grand unified theory scale. Superparticle masses of the visible sector from gravity/anomaly mediation are suppressed, and they are purely generated by the usual gauge mediation on the visible brane. Importantly, the Higgs Bμ-term vanishes at the leading order, which enables us to obtain the suitable μ-Bμ relation for the electroweak symmetry breaking. We discuss such models considering two possibilities of the SUSY breaking source: (1) Scherk-Schwarz SUSY breaking which we call Scherk-Schwarz gauge mediation and (2) gravitational SUSY breaking localized on a hidden brane. In case (2), the cosmological moduli problem may be relaxed as well.
