|摘要||The simple correlation among three lepton flavor mixing angles (theta (12), theta (13), theta (23)) and the leptonic Dirac CP-violating phase delta is conventionally called a sum rule of lepton flavor mixing, which may be derived from a class of neutrino mass models with flavor symmetries. In this paper, we consider the solar lepton mixing sum rule theta (12) ae theta (12) (nu) + theta (13) cos delta, where theta (12) (nu) stems from a constant mixing pattern in the neutrino sector and takes the value of theta (12) (nu) = 45A degrees for the bi-maximal mixing (BM), for the tri-bimaximal mixing (TBM) or for the golden-ratio mixing (GR), and investigate the renormalization-group (RG) running effects on lepton flavor mixing parameters when this sum rule is assumed at a superhigh-energy scale. For illustration, we work within the framework of the minimal supersymmetric standard model (MSSM), and implement the Bayesian approach to explore the posterior distribution of delta at the low-energy scale, which becomes quite broad when the RG running effects are significant. Moreover, we also discuss the compatibility of the above three mixing scenarios with current neutrino oscillation data, and observe that radiative corrections can increase such a compatibility for the BM scenario, resulting in a weaker preference for the TBM and GR ones.|
