Abstract

We propose a model in which supersymmetric weak scale dark matter is charged under a U(1)_d dark gauge symmetry. Kinetic mixing between U(1)_d and hypercharge generates the appropriate hierarchy of scales needed to explain PAMELA and ATIC with a GeV scale force carrier and DAMA or INTEGRAL using the proposals of inelastic or exciting dark matter. Because of the extreme simplicity of this setup, observational constraints imply a number of unambiguous predictions, including the size of the hypercharge D-term vacuum expectation value.
