Heavy-to-light currents at NNLO in SCET and semi-inclusive image decay Original Research Article

We perform the two-loop matching calculation for heavy-to-light currents from QCD onto soft-collinear effective theory for the complete set of Dirac structures. The newly obtained matching coefficients enter several phenomenological applications, of which we discuss heavy-to-light form factor ratios and exclusive radiative decays, as well as the semi-inclusive decay image. For this decay, we observe a significant shift of the forward–backward asymmetry zero and find image for an invariant mass cut image.
