在最近提出的中微子混合的重正化模型中,在规范的标准模型的超对称扩展的背景下,在所有四个参数都是真实的的情况下,获得了与之间的相关性。在这里,我们考虑一个参数是复杂的,因此允许一个Diracphase和两个Majoranaphase。我们发现这种相关性作为函数的一个轻微的修改。对于一组给定的输入值,和,我们得到sin θ 22θ23和(无中微子双β衰变中的有效马约拉纳中微子质量)作为tan δCP的函数。我们发现,该模型的结构总是产生小|tan δCP|.
In a recently proposed renormalizable model of neutrino mixing using the non-Abelian discrete symmetryin the context of a supersymmetric extension of the standard model with gauged, a correlation was obtained betweenandin the case where all four parameters are real. Here we consider one parameter to be complex, thus allowing for one Diracphaseand two Majoranaphases. We find a slight modification to this correlation as a function of. For a given set of input values of,,, and, we obtain sin⁡22θ23 and(the effective Majorana neutrino mass in neutrinoless double beta decay) as functions of tan⁡δCP. We find that the structure of this model always yields small |tan⁡δCP|.
