Abstract
The 130 GeV gamma-ray line based on tentative analyses on the Fermi-LAT data is hard to be understood with dark matter annihilation in the conventional framework of the MSSM. We point out that it can be nicely explained with two body decay of a scalar dark matter (ÏËDMâγγ) by the dimension 6 operator suppressed with the mass of the grand unification scale (â¼1016GeV), Lâ|ÏËDM|2FμνFμν/MGUT2, in which the scalar dark matter ÏËDM develops a TeV scale vacuum expectation value. We propose a viable model explaining the 130 GeV gamma-ray line.
