This research proposal studies the dark matter theories and phenomenologies, as well as experimental tests: systematically study the dark matter models such as isospin violation dark matter models, which can satisfy the constraints from the direct detection experiments, for example, the LUX, PandaX,and XENON1T experiments, etc., and discuss their experimental tests, especially the tests by the LHC and future collider experiments, etc. Systematically study various dark matter models which can explain the positron excesses etc. observed by the dark matter indirect detection experiments, discuss their phenomenological consequences, and solve the fine-tuning problem in the resonant dark matter models. In the supersymmetric Standard Models, systematically study various dark matter particle candidates and their tests by the collider experiments, etc. Systematically study the unification of the dark matter particle and inflaton, and solve the reheating problem. Systematically study the axion model building and phenomenology, as well as the effect on axion physics from the Grand Unified Theory monopoles. Systematically study the new methods to probe dark matter. Systematically study the asymmetric dark matter models, and discuss their phenomenological tests. Systematically study the multi-component dark matter models, and discuss their phenomenological tests. Systematically study the cosmic ray models and discuss the dark matter indirect detections. Systematically study the primordial black hole dark matter, and the cosmological productions of the primordial black holes, etc.
