We study neutrino oscillations in a medium of dark matter which generalizes the standard matter effect. A formula is derived to describe the effect of medium and its mediator to neutrinos. Neutrinos and anti-neutrinos receive opposite contributions from asymmetric distribution of (dark) matter and anti-matter, and thus it could appear in precision measurements of neutrino or anti-neutrino oscillations. Furthermore, it leads to an amusing possibility that neutrino oscillations can occur from the dark-matter-induced flavorful potential even for massless neutrinos.

暗物质中的中微子振荡
我们研究了暗物质介质中的中微子振荡,该介质概括了标准物质的作用。得出一个公式来描述介质及其介体对中微子的影响。中微子和反中微子从(暗)物质和反物质的不对称分布中获得相反的贡献,因此它可能出现在中微子或反中微子振荡的精确测量中。此外,这导致了一个有趣的可能性,即即使对于无质量的中微子,由暗物质引起的风味电位也可能发生中微子振荡。
