Introduction
============

Models with extra dimensions provide several interesting mechanisms for supersymmetry (SUSY) breaking. These mechanisms seem to make essential use of the presence of extra dimensions, which are not obviously realizable in a simple four dimensional setup. Recently, Arkani-Hamed, Cohen and Georgi [@ACG] and also Hill, Pokorski and Wang [@Fermi1] argued that it might be possible to translate many higher dimensional effects into a purely 4D construction by using a set of 4D theories which in the IR reproduce a the dynamics of the extra dimensional theory.[^2] These theories are also useful tools to regulate the higher dimensional theories, and even give a UV completion of them [@ACG; @Fermi1; @Fermi2] (see also [@otherlattice]).

The aim of this paper is to give a fully 4D implementation of a higher dimensional mechanism for supersymmetry breaking (gaugino mediation), using a 4D ${\cal N}=1$ SUSY model which at low energies is equivalent to a latticized version of these higher dimensional models. In order to do so we first show how to construct the higher dimensional supersymmetric theories from a 4D “moose” (lattice) approach.
