Recent Perturbative Results on Heavy Quark Decays
Abstract
We present new results for heavy quark decays at next-to-next-to-leading order. In particular, we discuss the calculation of the charm-quark mass effects and the expansion in the intermediate recoil limit in semi-leptonic bottom-quark decays and the evaluation of the helicity fractions of the W boson from top-quark decays.
