最大CP破坏假设与轻子混合矩阵

Maximal CP Violation Hypothesis and a Lepton Mixing Matrix

Yoshio Koide, Hiroyuki Nishiura

摘要:

最大CP破坏假设应用于一个简单轻子混合矩阵U= V_{CKM} ^ \dagger U_{TB},最近有人推测U在夸克混合矩阵V_{CKM} \to { \bf 1}的极限下成为一个精确的三重最大混合U_{TB}.在精确的三重极大混合U= U_{TB}的情况下,预测\tan^2 θ_{1/2} =1/2在推测的混合U = V_{CKM} ^ \dagger U_{TB}的情况下被大大地破坏了。然而,如果采用原来的Kobayashi-Maskawa相位约定,将该假设应用于轻子扇区,则可以将扰动值恢复到V_{CKM} θ_{1/2} \simeq 1/2。

英文摘要:

Maximal CP violation hypothesis is applied to a simple lepton mixing matrix form U=V_{CKM}^\dagger U_{TB}, which has recently been speculated under an ansatz that U becomes an exact tribimaximal mixing U_{TB} in a limit of the quark mixing matrix V_{CKM} \to {\bf 1}. The prediction \tan^2 θ_{12} =1/2 in the case of the exact tribimaximal mixing U=U_{TB} is onsiderably spoiled in the speculated mixing U=V_{CKM}^\dagger U_{TB}. However, the application of the hypothesis to the lepton sector can again recover the spoiled value to \tan^2 θ_{12} \simeq 1/2 if the original Kobayashi-Maskawa phase convention for V_{CKM} is adopted.
