Although the Standard Model, which appeared nearly half a century ago, has been very successful in explaining the numerous (thousands of) phenomena of elementary particle physics, we believe that it is not the complete and ultimate theory that describes our Nature. For one, it does not include gravitation in the theory, and for another, it does not have anything to say about the dark matter. On the other hand, there are mounting evidences of dark matter from astrophysical observations. Therefore, many dedicated experiments are on-going to search for dark matter and find their particle properties.
The Belle and Belle II are e+e- collistion experiments using the facilities (KEKB collider for Belle, and SUperKEKB collider for Belle II) in KEK, Japan. KEKB was the most luminous collider until a new luminosity record has been obtained by SuperKEKB. The Belle experiment has been very successful in discoverying CP violation in the B-meson systems, observing numerous new rare decays and exotic hadrons, thus enhancing greatly our understanding of flavor physics. In this talk, we present studies of dark sector physics at the Belle and Belle experiment.
