Signatures of Dipolar Dark Matter on indirect detection

Abstract 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 process χ ¯ → γ is computed starting from general form coupling }\gamma in framework an extension Standard Model. By taking into account matter pairs mono-energetic photons, found that for masses O (10 2 GeV, moment ∼10 −16 e cm required to satisfy current relic density inferences. Additionally, order pin down models viable describe physics at early Universe, also constrain our model according recent measurements temperature anisotropies cosmic microwave background radiation, report constraints moments range within model.
