Models and Phenomenology for Standard and Non-Standard Neutrino Physics

研究标准和非标准中微子物理的模型和唯象。对于标准物理学，将解释中微子振荡实验中新的精确数据的含义。目前未知的参数，如轻子CP相位，中微子质量排序或八分圆的大气混合角将在模型的框架内解释，并调查在什么方面的不一致。关于非标准物理学，质量在eV左右的轻无菌中微子将在模型中实现，并且将研究如何确定它们的属性。质量在keV左右的不育中微子是暖暗物质的候选者;这里可以遵循与轻不育中微子类似的方法。将分析是否可以在具体模型中获得必要的暗物质密度，例如在具有额外空间维度的框架中。最后，它将研究如何KATRIN实验可以约束新的物理，如右手电流或千电子伏的无菌中微子，以及如何将其与该物理的其他限制（轻子数和味违反，对撞机物理）进行比较，无论是在一般情况下还是在具体模型中。

Models and phenomenology of Standard and Non-standard neutrino physics are supposed to be studied. For standard physics, implications of new precision data in neutrino oscillation experiments will be interpreted. Currently unknown parameters such as the leptonic CP phase, the neutrino mass ordering or the octant of the atmospheric mixing angles will be explained in the framework of models, and investigated in what regards inconsistencies. Regarding non-standard physics, light sterile neutrinos with masses around eV will be implemented in models, and it is to be studied how their properties can be determined. Sterile neutrinos with masses around keV are candidates for warm dark matter; here similar approaches as for light sterile neutrinos can be followed. It is to be analysed if the necessary dark matter density can be obtained in concrete models, e.g. in frameworks with additional spatial dimensions. Finally, it will be investigated how the KATRIN experiment can constrain new physics such as right-handed currents or keV sterile neutrinos, and how this compares with other limits on that physics (lepton number and flavor violation, collider physics), both in general and in concrete models.
