Constraining heavy decaying dark matter with the high energy gamma-ray limits [HEAP]

http://arxiv.org/abs/1606.07354


We consider decaying dark matter with masses $10^{7} < M < 10^{16}$ GeV, as a source of ultra-high energy (UHE) gamma rays. Using recent limits on UHE gamma-ray flux for energies $E > 2 \cdot 10^{14}$ eV, provided by extensive air shower observatories, we put limits on masses and lifetimes of the dark matter.
