title: QCD corrections to [Formula: see text] in FDR.
abstract: I apply FDR-a recently introduced four-dimensional approach to quantum field theories (QFTs)-to the computation of the NLO QCD corrections to [Formula: see text] in the large top mass limit. The calculation involves all key ingredients of QCD-namely ultraviolet, infrared, and collinear divergences, besides [Formula: see text] renormalization-and paves the way for successful use of FDR in massless one-loop QFT computations. I show in detail how the correct result emerges in FDR, and discuss the translation rules to dimensional regularization.
