摘要：
We report measurements of the electroweak penguin decays of B mesons at the Belle detector, based on a data sample containing 65 million BB. We perform a precise measurement of B --> K*(892)gamma and a search for the b --> dgamma decay. We also analyze the b --> sl(+)l(-) process using exclusive and inclusive modes. We measure the inclusive b --> sl(+)l(-) rate for the first time with the branching fraction of (6.1 +/- 1.4(-1.1)(+1.3)) x 10(-6).
