Description

After the discovery of the Higgs boson the precise determination of its properties has become a priority. These precision studies often involve the decay of the Higgs boson to bottom quarks, since it is the predominately decay channel. In this talk I will present the calculation of the exact mixed EW-QCD corrections to this decay, which improves upon the existing approximate calculation. In particular I will elaborate on the treatment of $\gamma_5$, the calculation of the exact master integrals and the renormalization procedure. I will conclude by presenting how this inclusive calculation could be extended to differential observables.
