论文摘要
Sommerfeld增强功能在暗物质（DM）物理学中起着重要作用，并且可以显着增强非相关DM颗粒的an灭横截面。在本文中，我们研究了中微子力的影响，中微子是通过交换一对光中微子对Sommerfeld增强的影响。我们证明，在某些情况下，中微子可以对Sommerfeld增强作用显着校正。还简要讨论了可以实现DM-中性相互作用和相当大的Sommerfeld增强功能的模型，以及对中微子DM现象学的影响。
The Sommerfeld enhancement plays an important role in dark matter (DM) physics, and can significantly enhance the annihilation cross section of non-relativistic DM particles. In this paper, we study the effect of neutrino forces, which are generated by the exchange of a pair of light neutrinos, on the Sommerfeld enhancement. We demonstrate that in certain cases, a neutrino force can cause a significant correction to the Sommerfeld enhancement. Models that can realise DM-neutrino interactions and sizeable Sommerfeld enhancement are also briefly discussed, together with the impacts on DM phenomenology of neutrino forces.
