中微子和暗物质物理的关联研究

探索中微子质量起源机制和大量存在宇宙中的暗物质本质是寻找超出粒子物理标准模型新物理的直接途径，中微子和暗物质物理均已成为当前高能物理前沿研究的重要课题。本项目主要结合中微子质量起源机制和暗物质粒子本质，重点研究两者之间的内在关联，紧密结合各种中微子实验、暗物质探测实验以及对撞机实验数据，开展以下理论研究：中微子质量起源和暗物质粒子产生机制的统一研究，系统研究含有暗物质粒子的圈图层次跷跷板机制模型实现和相关唯象学，以及keV惰性中微子作为暗物质的机制和唯象学；跷跷板机制中新粒子自由度作为暗物质和物质间相互作用的媒介粒子简单化模型唯象研究；太阳中微子束流作为暗物质间接探测探针的研究。项目的开展可促进我们对超出标准模型新物理的进一步认识。

The origin mechanism of neutrino mass and the identity of dark matter particle are very interesting puzzles. Both of them lead directly to the new physics beyond the standard model. Neutrino physics and dark matter physics have become important frontiers of high energy physics. This project focuses on the interplays between neutrino and dark matter physics, try to understand the origin of neutrino mass and the nature of dark matter particles. With the help of the data from lots of active neutrino/dark matter and collider experiments, we plan to study the common origin of neutrino mass and dark matter particles, scotogenic neutrino mass model building and its phenomenology, as well as the case where keV sterile neutrino behaves as dark matter candidate. We will study the phenomenology of the triplet Higgs/sterile neutrino portal dark matter simplified models. We will also study the scenarios using the solar neutrino as the probe to indirectly search dark matter. This project is helpful to understand the nature of new physics beyond the standard model.
