低能非幺正轻子混合矩阵是一个大类理论占中微子质量的一般效果。它示出了如何额外的CP-奇相位的一般非酉矩阵允许相当大的CP-不对称性的渠道以外的标准酉的情况下占主导地位。νμ→ντ通道被证明是进一步约束模量和相位的极好工具。此外，我们澄清了我们的方法和所谓的“非标准中微子相互作用”计划之间的关系：这里探讨的敏感性也适用于这样的建设。
A low-energy non-unitary leptonic mixing matrix is a generic effect of a large class of theories accounting for neutrino masses. It is shown how the extra CP-odd phases of a general non-unitary matrix allow for sizeable CP-asymmetries in channels other than those dominant in the standard unitary case. The νμ→ντchannel turns out to be an excellent tool to further constrain moduli and phases. Furthermore, we clarify the relationship between our approach and the so-called “non-standard neutrino interactions” schemes: the sensitivities explored here apply as well to such constructions.
