Explaining the Fermi Galactic Centre Excess in the CMSSM
  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.
