Description
I will discuss refactorization conditions between the subleading power contributions to the inclusive B decay into photon suffering from endpoint divergences. I will also prove factorization theorem beyond leading power. This result allows for higher-order calculations of the resolved contributions and consistent summation of large logarithms. This is an example of first endpoint factorisation in a heavy flavor application of SCET, which includes nonperturbative functions as additional subtlety typically not present in collider applications.
