The calculation of the effective section of the process χχbar→γγ is made starting from a general form of coupling χ χbar γ in the framework of an extension of the Standard Model. We found, when taking into account an annihilation of DDM-antiDDM to monoenergetic photons, that for small masses, m<sub>χ</sub> ≤ 0 GeV, an electric dipole moment ~10<sup>–6</sup> e cm is required to satisfy the current residual density, while for the range of greater sensitivity of HAWC, 10 TeV &lt; E<sub>g</sub> &lt; 20 TeV, the electrical dipole moment must be of the order of 10<sup>–8</sup> e cm.</p> ER -
