质量矩阵结构中的中微子振荡观测

Neutrino Oscillation Observables from Mass Matrix Structure

Walter Winter

摘要:

我们提出了一个系统的程序来建立复杂的中微子质量矩阵纹理和实验观测值,包括狄拉克CP相位之间的连接。此外,我们说明了未来的实验测量如何影响(θ_13,delta_CP)平面中纹理的选择。对于混合角,我们使用一般的假设激发夸克轻子互补。我们允许U_l和U_nu之间的任何组合,以及我们对所有当前复杂相位进行平均。我们发现,个别纹理导致非常不同的分布的观察,如大或小轻子CP破坏。此外,我们发现,扩展的夸克-轻子互补的方法,激励未来的精度测量的delta_CP在theta_C \simeq 11度的水平。

英文摘要:

We present a systematic procedure to establish a connection between complex neutrino mass matrix textures and experimental observables, including the Dirac CP phase. In addition, we illustrate how future experimental measurements affect the selection of textures in the (theta_13,delta_CP)-plane. For the mixing angles, we use generic assumptions motivated by quark-lepton complementarity. We allow for any combination between U_l and U_nu, as well as we average over all present complex phases. We find that individual textures lead to very different distributions of the observables, such as to large or small leptonic CP violation. In addition, we find that the extended quark-lepton complementarity approach motivates future precision measurements of delta_CP at the level of theta_C \simeq 11 degrees.
