Abstract :
We present an independent calculation of that part of the image contribution to the decay width image which arises from the self-interference term of the electromagnetic dipole operator image. Using a different method, we find complete agreement with a previous calculation. This NNLL contribution is an important ingredient for the complete NNLL prediction of image which will resolve the charm quark mass ambiguity appearing at NLL accuracy.
