论文摘要
了解费米昂混合矩阵的结构是粒子物理学的重要问题。夸克混合矩阵大约是对角线的，而Lepton混合矩阵具有较大的非对角性元素。在过去的几十年中，试图理解这些结构一直是大量文学的重点。在本文中，我们提出了一组新的条件，以基于混合矩阵的对角线程度来测试称为正常的质量矩阵结构。 $θ_{23} $的质量顺序和八分之一代表其中两个条件。我们指出，夸克矩阵很容易满足所有六个正常条件，而夸克矩阵对具有很高意义的瘦素完全满足。可以测试的所有条件都表明基质可以满足正常情况和即将进行的实验，例如Dune和T2HK，很可能会确定Lepton Mass Matrix是否满足所有它们。
Understanding the structure of the fermion mixing matrices is an important question in particle physics. The quark mixing matrix is approximately diagonal while the lepton mixing matrix has large off-diagonal elements. Attempting to understand these structures has been the focus of an large body of literature over the last several decades. In this article we propose a new set of conditions to test the structure of mass matrices called normalcy based on how close to diagonal the mixing matrix is. The mass ordering and the octant of $θ_{23}$ represent two of these conditions. We point out that the quark matrix easily satisfies all six normalcy conditions while none of them are known to be fully satisfied for leptons at high significance. All of the conditions that can be tested for leptons suggest that the matrix could satisfy the normalcy conditions and upcoming experiments such as DUNE and T2HK will most likely determine if the lepton mass matrix satisfies all of them or not.
