非零中微子质量将在标准模型之外提供有关粒子物理的新的、独特的信息。中微子味振荡为直接测试小质量中微子提供了最灵敏的方法。当振荡发生在物质中时，可能会发生共振，极大地增强味道混合，并可能导致从一种中微子味道转换到另一种味道。这是一个解决长期存在的“太阳中微子问题”的诱人方案。综述了物质中的中微子振荡现象。详细讨论了中微子味在物质中存活几率的解析描述。讨论了中微子振荡在太阳、地球、超新星和早期宇宙物质中的应用。
Nonzero neutrino masses would provide new, unique information on particle physics beyond the standard model. Neutrino flavor oscillations provide the most sensitive method for directly testing for small neutrino masses. When the oscillations occur in matter, a resonance can occur that dramatically enhances the flavor mixing and can lead to conversion from one neutrino flavor to another. This is an attractive solution to the long-standing "solar neutrino problem." The phenomenon of neutrino oscillations in matter is reviewed. Analytic descriptions of the neutrino flavor survival probability in matter are considered in detail. A discussion is given for applications of neutrino oscillations in matter for the sun, Earth, supernovae, and the early universe.
