| Research Abstract |
As one of the measurements for the Belle experiment which aims for the verification of the Kobayashi-Maskawa theory and for the search for the New Physics, the study of radiative B meson decays using semi-inclusive method, in which many exclusive final states are summed up in the reconstruction, has been performed. The analysis method has been optimized to suppress the background effectively. The measurement precision in the future Belle II, which will collect 50 times more data than Belle, has been estimated
