N2 - In this work, we study the annihilation of fermionic dark matter, considering it as a neutral particle with non-vanishing magnetic (M) and electric (D) dipole moments. Effective cross section of the process χ χ ¯ → γ γ is computed starting from a general form of the coupling χ χ ¯ γ in the framework of an extension of the Standard Model. By taking into account the annihilation of dark matter pairs into mono-energetic photons, we found that for masses of O(102) GeV, an electric dipole moment ∼10−16 e cm is required to satisfy the current relic density inferences. Additionally, in order to pin down models viable to describe the physics of dark matter at the early Universe, we also constrain our model according to recent measurements of the temperature anisotropies of the cosmic microwave background radiation, and report constraints to the electric and magnetic dipole moments for a range of masses within our model.
