Abstract

We present a theoretical prediction for the photon spectrum in radiative [Formula presented] decay including the effects of resumming the end point region, [Formula presented]. Our approach is based on nonrelativistic QCD (NRQCD) and the soft-collinear effective theory. We find that our results give much better agreement with data than the leading order NRQCD prediction.
