Summary
Dark matter is known to occupy a quarter of the total energy of the universe according to cosmic observations. However, we don’t know any characteristics of dark matter as a particle. In particular, we don’t know “how heavy is a dark matter?” and “how does it interact with other particles?” Reveling the characteristics of dark matter is one of the crucial subjects in elementary particle physics and also in astrophysics. Dark matters are localized around our galaxy. They should exist around us with almost no interactions with us. Therefore, in the decades, many experiments have searched for dark matter on the earth. However, no one still has detected it. I search for dark matter with a new method using millimeter-wave light on the earth. The experiment is named “DOSUE-RR (Dark-photon Observing System for Un-Explored Radio-Range)”. I will talk about how to detect dark matter in this experiment and also recent results and future prospects.
