Power-enhanced leading-logarithmic QED corrections to B q → μ + μ −

Abstract We provide a systematic treatment of the previously discovered power- enhanced QED corrections to the leptonic decay B q → μ + μ − (q = d, s) in the frame- work of soft-collinear effective theory (SCET). Employing two-step matching on SCETI and SCETII, and the respective renormalization gro...
