用“双大”轻子混合矩阵预测中微子振荡

Predicting neutrino oscillations with "bi-large" lepton mixing matrices

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

摘要:

本文提出了轻子混合矩阵$U = U_l^\dagger U_ν$的两种方案,其中$U = U_l$表示带电扇区,$U_ν$表示中微子对角化矩阵.我们假设$U_ν$是CP守恒的,并且它的三个角以简单的方式与Cabibbo角相连。CP破坏仅由$U_l$产生,假定具有统一建议的CKM形式$U_l\simeq V_{\rm CKM}$。振荡参数取决于一个单一的参数,导致狭窄的范围内的“太阳”和“加速器”的角度$θ_{12}$和$θ_{23}$,以及CP阶段,预测为$δ_{\rm CP}\sim 1.3π$。

英文摘要:

We propose two schemes for the lepton mixing matrix $U = U_l^\dagger U_ν$, where $U = U_l$ refers to the charged sector, and $U_ν$ denotes the neutrino diagonalization matrix. We assume $U_ν$ to be CP conserving and its three angles to be connected with the Cabibbo angle in a simple manner. CP violation arises solely from the $U_l$, assumed to have the CKM form, $U_l\simeq V_{\rm CKM}$, suggested by unification. Oscillation parameters depend on a single parameter, leading to narrow ranges for the "solar" and "accelerator" angles $θ_{12}$ and $θ_{23}$, as well as for the CP phase, predicted as $δ_{\rm CP}\sim 1.3π$.
