在中微子工厂检验中微子混合矩阵的非么正性

Testing non-unitarity of neutrino mixing matrices at neutrino factories

Srubabati Goswami, Toshihiko Ota

摘要:

本文研究了非幺正中微子混合对真空和物质中中微子振荡几率的影响。特别是,我们考虑的$ν_μ\to ν_τ$通道和使用中微子工厂作为源$ν_μ$的讨论的限制,可以得到的模和相位的参数特征违反么正性。我们指出如何新的CP破坏阶段目前的情况下,非幺正混合产生虚假的“退化”的解决方案,在参数空间和讨论如何真正的解决方案可以通过结合测量在几个基线。

英文摘要:

In this paper we explore the effect of non-unitary neutrino mixing on neutrino oscillation probabilities both in vacuum and matter. In particular, we consider the $ν_μ\to ν_τ$ channel and using a Neutrino Factory as the source for $ν_μ$'s discuss the constraints that can be obtained on the moduli and phases of the parameters characterizing the violation of unitarity. We point out how the new CP violation phases present in the case where the non-unitary mixings give rise to spurious ``degenerate'' solutions in the parameter space and discuss how the true solutions can be extricated by combining measurements at several baselines.
