Radiative decays b→s gamma and b→d gamma occur through penguin loops and are very sensitive probes of the Standard Model. Using 150 million BBbar pairs, the Belle experiment recently reported about an inclusive measurement of the b→s gamma decay, a first evidence for the Cabibbo-suppressed b→d gamma decay and CP violation measurements in radiative decays. The speaker will discuss these results, highlighting the inclusive b→s gamma measurement.
