摘要

高精度的轻子混合参数和下一代中微子望远镜使高能天体物理中微子(HAN)风味跃迁的新物理测试成为可能。我们引入了一个非对称矩阵来修正标准风味转移矩阵的预测。它是由真空中的混合矩阵和HAN源处的混合矩阵构成的。混合矩阵的不匹配导致了对地球上HAN的风味比的新期望。它还会导致一种次要效应,称为表观P违逆(APV)。对新效应进行了定量分析,并在HAN源处设置了适当的参数。给出了混合参数与新预测结果之间的相关性。从相关关系中,确定了决定新物理效应的主要参数。

The Nonsymmetric Flavor Transition Matrix and the Apparent P Violation
The leptonic mixing parameters of high precision and the next-generation neutrino telescopes make it possible to test new physics in the flavor transition of the high-energy astrophysical neutrinos (HAN). We introduce a nonsymmetric matrix to modify the predictions of the standard flavor transition matrix. It is constructed with the mixing matrix in vacuum and that at the source of the HAN. The mismatch of the mixing matrices results in the new expectation of the flavor ratio of the HAN at Earth. It also leads to a secondary effect called the apparent P violation (APV). The quantitative analyses of the new effects are performed with a moderate setup of the parameters at the source of the HAN. The correlations between the mixing parameters and the new predictions are shown. From the correlations, the dominant parameters determining the new-physics effects are identified.
