三重极大中微子混合的有限量子修正

Finite quantum corrections to the tribimaximal neutrino mixing

Takeshi Araki, Chao-Qiang Geng, Zhi-zhong Xing

摘要:

本文在三类中微子质量模型中计算了对三重最大中微子混合模式V_TB的有限量子修正。结果表明,三种味混合角都能偏离VTB描述的树级结果,其中θ 12对这种量子效应最为敏感,Dirac CP破坏相可以由两个Majorana CP破坏相辐射产生.这一理论方案为理解θ 13自然小的原因以及三个CP破坏相之间的关联提供了一种新的途径。

英文摘要:

We calculate finite quantum corrections to the tribimaximal neutrino mixing pattern V_TB in three generic classes of neutrino mass models. We show that three flavor mixing angles can all depart from their tree-level results described by V_TB, among which θ_12 is most sensitive to such quantum effects, and the Dirac CP-violating phase can radiatively arise from two Majorana CP-violating phases. This theoretical scheme offers a new way to understand why θ_13 is naturally small and how three CP-violating phases are presumably correlated.
