Internal Bremsstrahlung Signature of Real Scalar Dark Matter and Consistency with Thermal Relic Density
Internal Bremsstrahlung Signature of Real Scalar Dark Matter and Consistency with Thermal Relic Density
A gamma-ray excess from the galactic center consistent with line emission around 130 GeV was recently found in the Fermi-LAT data. Although the Fermi-LAT Collaboration has not confirmed its significance, such a signal would be a clear signature of Dark Matter annihilation. Until now, there have been many attempts to …
