标题： Neutrinos: Windows to Planck Physics

摘要： 在回顾了已故Freydoon Mansouri的一些优雅贡献后，我们转向中微子物理，并使用一个大统一的{\it 适度}来关联夸克和轻子混合矩阵。 我们提倡对MNS矩阵进行展开，{\it 按照}Wolfenstein，并认为在一大类模型中，$\theta_{13}$是一个Cabibbo混合效应。 此外，大的中微子混合角反映了接近普朗克尺度的右手中微子的质量模式，并为该尺度上的家族结构提供了证据。 显示英文摘要

摘要： After recalling some elegant contributions of the late Freydoon Mansouri, we turn to neutrino physics and use a {\it modicum} of grand unification to relate quark and lepton mixing matrices. We advocate an expansion for the MNS matrix, {\it \`a la} Wolfenstein, and argue that in a wide class of models, $\theta_{13}$ is a Cabibbo mixing effect. Also the large neutrino mixing angles reflect the mass patterns of the right-handed neutrinos near the Planck scale, and provide evidence for family structure at that scale.
