image two-loop electroweak correction to Higgs-boson decay to bottom quarks Original Research Article

We analytically calculate the dominant two-loop electroweak correction, of image, to the partial width of the decay of a Higgs boson, with mass image, into a bottom-quark pair, and describe the most important conceptual and technical details of our calculation. As a by-product of our analysis, we also recover the image correction. Relative to the Born result, the image correction turns out to be approximately image and, thus, more than compensates the image one, which amounts to approximately image.
