Inclusive and exclusive $b\to s/d\gamma$

Abstract

In this article, I review the recent results for inclusive and exclusive measurements for $b\to s\gamma$ and $b\to d\gamma$ decays from $B$ factories Belle and Babar. I describe the measurement of branching fraction and direct CP violating asymmetry for inclusive $B\to X_s\gamma$ decay. For results of $b\to d\gamma$ process, I introduce the measurement of branching fraction of exclusive $b\to d\gamma$ modes, the first measurement for CP asymmetry of $b\to d\gamma$ process using $B\to\rho\gamma$ mode, and semi-inclusive measurement for $B\to X_d\gamma$.
