摘要
文献中已研究中微子振荡实验中CP破坏可观测量的测量，作为确定轻子混合矩阵中CP破坏相的一种方法。在此我们表明，此类可观测量也能探测产生或探测过程中的新中微子相互作用。由物质效应引起的真正CP破坏和假CP破坏对新耦合的虚部和实部敏感。CP不对称性对源-探测器距离的依赖关系不同于标准情况，并且在短距离处特别增强。我们估计，未来的中微子工厂将能够以这种方式探测比弱相互作用弱达四个数量级的新相互作用。我们讨论了对新物理模型的可能意义。

ReVTeX, 28 pages, 7 figues. v2: Modifications in section VIII to reflect the fact that some of the couplings that were discussed in this section are irrelevant to our analysis (as pointed out in hep-ph/0112329); Added a discussion in section IX of the relevance of other future experiments that will search for lepton flavor violation
