中微子混合与夸克混合之间的一个简单的大统一关系

A Simple Grand Unified Relation between Neutrino Mixing and Quark Mixing

S. M. Barr, Heng-Yu Chen

摘要:

我们认为所有的味混合都是由SU(5)的5 + 5-bar多重态中的三个夸克族和轻子族与矢量类费米子的混合引起的。这个简单的假设意味着V_{CKM}和U_{MNS}都是由单个矩阵生成的。然后发现中微子M_{nu}的整个3 × 3复质量矩阵有两个复参数和一个总尺度的简单表达式。因此,所有目前未知的中微子参数的预测。对于小于或大约40度的theta_{atm},最佳拟合。轻子狄拉克CP相位被发现是略大于π弧度。

英文摘要:

It is proposed that all flavor mixing is caused by the mixing of the three quark and lepton families with vectorlike fermions in 5 + 5-bar multiplets of SU(5). This simple assumption implies that both V_{CKM} and U_{MNS} are generated by a single matrix. The entire 3-by-3 complex mass matrix of the neutrinos M_{nu} is then found to have a simple expression in terms of two complex parameters and an overall scale. Thus, all the presently unknown neutrino parameters are predicted. The best fits are for theta_{atm} less than or approximately 40 degrees. The leptonic Dirac CP phase is found to be somewhat greater than pi radians.
