Annihilation of Dipolar Dark Matter: χχ→γγ
Journal Title: Journal of Nuclear Physics, Material Sciences, Radiation and Applications - Year 2018, Vol 6, Issue 1
Abstract
In this work we study the annihilation of dark matter, considering it as a neutral particle with magnetic and/or electric moments not null. The calculation of the effective section of the process χχbar→γγ → is made starting from a general form of coupling χχbar 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, mχ ≤ 0 GeV, an electric dipole moment ~10–6 e cm is required to satisfy the current residual density, while for the range of greater sensitivity of HAWC, 10 TeV < Eg < 20 TeV, the electrical dipole moment must be of the order of 10–8 e cm.
