Abstract

The Super-Kamiokande and T2K experiments substantially developed our understanding of oscillations by observing the subdominant electron-neutrino appearance channel. The next-generation Hyper-Kamiokande experiment will build on this with much higher statistics, enabling precision tests of the Standard PMNS picture. In the baseline design of 2 tanks at Kamioka, a detailed investigation of oscillations can be made in the vicinity of the first oscillation maximum, and at short baselines using the near detector. More interesting tests can be preformed if the second tank is located in Korea, as this give access to an $L/E$ regime that is three times higher than any previous long-baseline experiment. As well as benefits to the PMNS measurements, a new experimental regime makes it possible to resolve BSM models which are statistically degenerate on a single baseline. This talk focuses on three models: Lorentz violation with neutrinos; sterile neutrinos; and non-standard interactions.
超神冈和T2K超标准模型物理搜索的前景
超级神冈和T2K实验通过观察亚显性电子-中微子外观通道,极大地发展了我们对振荡的理解。下一代hyper -神冈实验将在此基础上建立更高的统计数据,使标准PMNS图像的精确测试成为可能。在神冈的2个储罐的基线设计中,可以在第一个振荡最大值附近和短基线处使用近探测器进行详细的振荡调查。如果第二辆坦克位于韩国,可以进行更有趣的测试,因为这可以获得比以往任何长期基线实验高三倍的L/E制度。除了对PMNS测量的好处外,一种新的实验制度使解决在单一基线上统计退化的BSM模型成为可能。本讲座主要讨论三个模型:中微子的洛伦兹破坏;惰性中微子;非标准的相互作用。
