Inclusive and exclusive $b\to s/dγ$

Abstract

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