论文摘要
对于Majoraana fermions，Anapole矩是唯一允许的电磁多极矩。在这项工作中，我们使用捏合技术来计算Yukawa和Majorana fermion在一环和仪表相互作用下诱导的Anapole矩，以确保结果的有限性和量规不利率。作为Majorana fermion的原型示例，我们计算了最小的超对称标准模型中最轻的中性诺的Anapole力矩，特别是在Bino，Wino和Higgsino限制中。最后，我们简要地讨论了以Majorana Fermions形式直接检测Anapole时刻对暗物质的含义。
For Majorana fermions the anapole moment is the only allowed electromagnetic multipole moment. In this work we calculate the anapole moment induced at one-loop by the Yukawa and gauge interactions of a Majorana fermion, using the pinch technique to ensure the finiteness and gauge-invariance of the result. As archetypical example of a Majorana fermion, we calculate the anapole moment for the lightest neutralino in the Minimal Supersymmetric Standard Model, and specifically in the bino, wino and higgsino limits. Finally, we briefly discuss the implications of the anapole moment for the direct detection of dark matter in the form of Majorana fermions.
