Towards a Realistic Type IIA T^6/Z_4 Orientifold Model with Background   Fluxes, Part 1: Moduli Stabilization
  We apply the methods of DeWolfe et al. [hep-th/0505160] to a T^6/Z_4 orientifold model. This is the first step in an attempt to build a phenomenologically interesting meta-stable de Sitter model with small cosmological constant and standard model gauge groups.
