实三-双-极大中微子混合

Realistic Tri-Bi-Maximal neutrino mixing

Peng Chen, Salvador Centelles Chuliá, Gui-Jun Ding, Rahul Srivastava, José W. F. Valle

摘要:

我们提出了一个广义的三-双-极大(TBM)模型,用于轻子混合,导致非零反应堆角$θ_{13}$和CP破坏。后者的特点是两个CP阶段。影响中微子振荡的狄拉克相位接近最大值($δ_{CP} \sim \pm π/2$),而马约拉纳相位意味着无中微子双β衰变振幅的允许范围很窄。太阳角$θ_{12}$接近其TBM值,而大气角$θ_{23}$具有最大$δ_{CP}$的TBM值。中微子振荡的预言可以在目前和即将进行的实验中得到检验。

英文摘要:

We propose a generalized version of the Tri-Bi-Maximal (TBM) ansatz for lepton mixing, leading to non-zero reactor angle $θ_{13}$ and CP violation. The latter is characterized by two CP phases. The Dirac phase affecting neutrino oscillations is nearly maximal ($δ_{CP} \sim \pm π/2$), while the Majorana phase implies narrow allowed ranges for the neutrinoless double beta decay amplitude. The solar angle $θ_{12}$ lies nearly at its TBM value, while the atmospheric angle $θ_{23}$ has the TBM value for maximal $δ_{CP}$. Neutrino oscillation predictions can be tested in present and upcoming experiments.
