Mixed Wino-Axion Dark Matter in String/M Theory and the 130 GeV
  Gamma-line "Signal"
  String/M theory compactifications with low energy supersymmetry tend to
predict that dark matter has two components: axions and WIMPs
\cite{1004.5138,1204.2795}. In accord with this, we show that the tentative 130
GeV gamma-line signal reported in \cite{1204.2797} can be interpreted as
arising from the annihilation of 145 GeV mass, Wino-like WIMPs into a Z-boson
and a photon. In this context, the signal implies a second component of dark
matter which we interpret as being composed of axions - the relative Wino/Axion
abundances being approximately equal. Further predictions are implied: signals
in both diffuse and monochromatic photons from dwarf spheroidal galaxies;
monochromatic photons with energy 145 GeV; for the LHC, the Higgs boson mass
has been predicted in this framework \cite{1112.1059}, and the current Higgs
limits provide interesting constraints on the mass of the Gluino.
