Inclusive and exclusive $bto s/dgamma$


Abstract in English

In this article, I review the recent results for inclusive and exclusive measurements for $bto sgamma$ and $bto dgamma$ decays from $B$ factories Belle and Babar. I describe the measurement of branching fraction and direct CP violating asymmetry for inclusive $Bto X_sgamma$ decay. For results of $bto dgamma$ process, I introduce the measurement of branching fraction of exclusive $bto dgamma$ modes, the first measurement for CP asymmetry of $bto dgamma$ process using $Btorhogamma$ mode, and semi-inclusive measurement for $Bto X_dgamma$.
