Study of Radiative B Decays in Belle
One of very interesting topics in the physics of B mesons are the radiative B decays, where a high energy photon is emitted in the decay of a B meson. This process proceeds through a one-loop penguin diagram, and is sensitive to the physics beyond the standard model; from the measured rate it is, e.g., possible to derive limits on the mass of the charged Higgs. Because these transitions are rare, it has not been possible until recently to investigate them in detail. The Belle experiment, at KEK in Japan, is particularly suited for studying such processes since it has accumulated a large sample of B mesons produced in the KEKB accelerator.
In the seminar, measurements of radiative B decays in Belle will be presented together with some most interesting results. Future prospects for the studies of New Physics using radiative B decays at the upgraded Belle II experiment will also be discussed.
