论文摘要
在本文中，我们探讨了中微子与暗物质之间的相互作用。特别是，我们研究了如何通过计算银河系背景产生的最一般电位来改变天体中微子的传播。我们使用壳技术以完全独立的方式来计算这一潜力，并获得对任何暗物质质量和自旋有效的表达式。之后，我们使用此表达在什么情况下分析这种潜力在现象学水平上可能很重要，并且我们发现，在某些假设下，只有超光标量的暗物质才能与振荡实验有关。
In this paper we explore interactions between neutrinos and Dark Matter. In particular, we study how the propagation of astrophysical neutrinos can be modified by computing the most general potential generated by the galactic DM background. We use on-shell techniques to compute this potential in a completely model independent way and obtain an expression valid for any Dark Matter mass and spin. Afterwards, we use this expression to analyse under what circumstances such potential can be important at the phenomenological level, and we find that under some assumptions only ultra light scalar Dark Matter could be of any relevance to oscillation experiments.
