Research Abstract

The purpose of this project is to acquire new insights into dark matter physics based on collider physics as well as on cosmological observations. Concerning the collider physics, a new method to measure the gravitino mass is proposed in the case where the gravitino is superlight, which is an important possibility in cosmology. In addition, from cosmology point of view, it has been discussed that the decay of dark matter can be a significant source of high energy cosmic rays. In addition, a detailed study of the Wino dark matter scenario is provided. Furthermore, implications of thermal effects on the evolution of the universe was also studied.
