Abstract
We use the ``general gauge mediation'' (GGM) formalism to describe a five-dimensional setup with an ${S}^{1}/{\mathbb{Z}}_{2}$ orbifold. We first consider a model independent supersymmetry breaking hidden sector on one boundary and generic chiral matter on another. Using the definition of GGM, the effects of the hidden sector are contained in a set of global symmetry current correlator functions and is mediated through the bulk. We find the gaugino, sfermion and hyperscalar mass formulas for minimal and generalized messengers in different regimes of a large, small and intermediate extra dimension. Then we use the five-dimensional GGM formalism to construct a model in which an $SU(5)$ Intriligator, Seiberg and Shih (ISS) model is located on the hidden boundary. We weakly gauge a global symmetry of the ISS model and associate it with the bulk vector superfield. Compared to four-dimensional GGM, there is a natural way to adjust the gaugino versus sfermion mass ratio by a factor $(M\ensuremath{\ell}{)}^{2}$, where $M$ is a characteristic mass scale of the supersymmetry breaking sector and $\ensuremath{\ell}$ is the length of the extra dimension.
