我们推导了中微子质量、轻子混合角和CP相位的重整化群运行的简单解析公式，使运行变得容易理解。特别是对于小角度 θ13，即使存在非零 CP 相位，表达式也会变得非常紧凑。使用这些方程，我们研究：(i) 狄拉克相和马约拉纳相对所有参数演化的影响，(ii) 运行中微子参数对轻子发生的影响，(iii) WMAP 和无中微子双 β 衰变实验的质量界限变化，与高能质量模型相关，(iv) θ13 和 θ23 的辐射校正的大小以及对未来精确测量的影响。
We derive simple analytical formulae for the renormalization group running of neutrino masses, leptonic mixing angles and CP phases, which allow an easy understanding of the running. Particularly for a small angle θ13the expressions become very compact, even when non-vanishing CP phases are present. Using these equations we investigate: (i) the influence of Dirac and Majorana phases on the evolution of all parameters, (ii) the implications of running neutrino parameters for leptogenesis, (iii) changes of the mass bounds from WMAP and neutrinoless double β decay experiments, relevant for high-energy mass models, (iv) the size of radiative corrections to θ13and θ23and implications for future precision measurements.
