论文摘要
在Capozzi等人最近的一项（Arxiv：1908.06992）的作品中，观察到，非标准中微子 - 摩擦相互作用的引入大大放松了T2K的偏好，而在标准的三中性风景标准中观察到的倒数质量是正常的no $ν$。在此注释中，我们更新了以前的全球拟合，以调查一旦考虑到太阳，大气和反应堆实验的信息，该结果是否仍然存在。我们发现，负责改善倒数的非标准参数拟合了T2K，而没有$ν$数据与其他振荡实验不兼容，并且恢复了NO的偏好。
In a recent work by Capozzi et al (arXiv:1908.06992), it is observed that the introduction of non-standard neutrino-matter interactions considerably relaxes the preference of T2K and NO$ν$A for normal over inverted mass ordering observed in the standard three-neutrino scenario. Motivated by this, in this note we update our previous global fit to investigate whether such result still holds once the information of solar, atmospheric and reactor experiments is taken into account. We find that the non-standard parameters responsible for the improvement of the inverted ordering fit to T2K and NO$ν$A data are not compatible with the other oscillation experiments, and that the preference for NO is restored.
