On the possibility of a 130 GeV gamma-ray line from annihilating singlet fermionic dark matter

T. H. Franarin, C. A. Z. Vasconcellos, D. Hadjimichef

There is evidence for a spectral line at $E_{\gamma }\approx 130$ GeV in the Fermi-LAT data that can be explained as dark mater particles annihilating into photons. We review a well known…
