Explaining the Fermi Galactic Centre Excess in the CMSSM

Abstract

We present an analysis of the compatibility between the Galactic Centre Excess (GCE) and the Constrained MSSM (CMSSM). We perform a global fit to the relevant experimental data including the GCE taking into account the systematic uncertainties. We find that the CMSSM is able to account for the GCE and maintain agreement with the other experimental searches, providing the first example that the GCE can be explained in the framework of universal supersymmetry. We map out the region compatible at 2 sigma and comment on its phenomenology. We find that for the CMSSM to explain the GCE the solution must lie close to the existing limits from LUX, IceCube and the LHC. We show that this provides definite predictions for Run 2 of the LHC, Xenon-1T and future observation with IceCube. Thus there exists the exciting possibility that the CMSSM could be observed in four distinct experimental channels over the next few years, which would be a striking signature for universal supersymmetry.
