Abstract
Analytical expressions are presented for contributions of order \(O(\overline \alpha \overline \alpha _s )\) and \(O(\overline \alpha ^2 )\) to the \(\bar bb\)-decay width of the neutral Higgs boson of the standard model of electroweak interactions. The numerical value of the mixed QED and QCD correction of order \(O(\overline \alpha \overline \alpha _s )\) is comparable to other computed terms in the perturbation series.
