Findings

Measured branching fractions for $B o X_s\gamma$ and $b o d\gamma$ modes.

First measurement of CP asymmetry in $b o d\gamma$ using $B o ho\gamma$.

Semi-inclusive measurement of $B o X_d\gamma$.

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 $B\to X_d\gamma$.
