Description
The inclusive radiative decay mode $B \to X_s \gamma$ provides an important channel for new physics searches.
When the photon energy is large, $m_b - 2 E_\gamma \sim \mathcal{O}(\Lambda_{\rm QCD})$, methods from soft-collinear EFT can be used to construct a systematic heavy-quark expansion.
In this talk, I will discuss how to include $\mathcal{O}(\alpha_s)$ corrections to the power-suppressed resolved-photon contribution from the $O_1 - O_7$ interference.
The perturbative scale uncertainty from this term makes up a large portion of the error budget of this process, which is expected to significantly reduce after taking into account radiative corrections.
