摘要
我们对偶极费米子粒子作为暗物质(DDM)的可行候选物的目的感兴趣。然后，我们研究了暗物质湮灭成光子，将其视为具有不消失的磁(M)和电(D)偶极矩的中性粒子。总湮灭截面 σ(χ →γ )是通过在超越标准模型(BSM)的框架中从一般形式的耦合χγ 开始计算的。我们发现，为了满足当前宇宙遗迹密度，需要O(mχ)∽102GeV, D≈10−16 e cm的候选粒子。
We are interested in the purpose of a dipolar fermionic particle as a viable candidate of Dark Matter (DDM). Then, we study the annihilation of dark matter into photons, considering it as a neutral particle with non-vanishing magnetic (M) and electric (D) dipolar moments. The total annihilation cross section σ(χ → γ ) is computed by starting from a general form of coupling χγ in a framework beyond to Standard Model (BSM). We found that candidates with O(mχ )∽102GeV, D≈10−16 e cm are required in order to satisfy the current cosmic relic density.
