Effective theory of dark matter decay into monochromatic photons and its implications: Constraints from associated cosmic-ray emission

We show that there exists only a quite limited number of higher dimensional operators which can naturally lead to a slow decay of dark matter particles into monochromatic photons. As each of these operators inevitably induces decays into particles other than photons, we show that the γ-lines it indu...
