| Research Abstract |
Radiative decay of B meson is known as one of the best places to look for New Physics beyond the Standard Model. By measuring photon polarization, we might derive effect of New Physics. Searches for New Physics by measuring parameters such as time-dependent CP asymmetry have been performed, however, no significant evidence has been found. On the other hand, sensitivity reaches in near-future experiments have been improved successfully.
