A description of the Galactic Center excess in the Minimal
  Supersymmetric Standard Model
  Observations with the Fermi Large Area Telescope (LAT) indicate an excess in
gamma rays originating from the center of our Galaxy. A possible explanation
for this excess is the annihilation of Dark Matter particles. We have
investigated the annihilation of neutralinos as Dark Matter candidates within
the phenomenological Minimal Supersymmetric Standard Model (pMSSM). An
iterative particle filter approach was used to search for solutions within the
pMSSM. We found solutions that are consistent with astroparticle physics and
collider experiments, and provide a fit to the energy spectrum of the excess.
The neutralino is a Bino/Higgsino or Bino/Wino/Higgsino mixture with a mass in
the range $84-92$~GeV or $87-97$~GeV annihilating into W bosons. A third
solutions is found for a neutralino of mass $174-187$~GeV annihilating into top
quarks. The best solutions yield a Dark Matter relic density $0.06 < \Omega h^2
<0.13$. These pMSSM solutions make clear forecasts for LHC, direct and indirect
DM detection experiments. If the MSSM explanation of the excess seen by
Fermi-LAT is correct, a DM signal might be discovered soon.
