The presence of the e ective coupling alters the renormalization scale dependence of the hard subprocess cross section, compared to full QCD. For a xed renormalization scale 0, the cross section for single Higgs production processes via gluon fusion with n nal state jets at leading order can be written in terms Webfor gluon bremsstrahlung vanishes, resulting in large logarithmic corrections. This is a natural feature of QCD in higher order perturbation theory, that large corrections emerge in the edges of phase space. We obtain this behavior of QCD in all calculations discussed in this PhD thesis. If we try to get sensible answers from QCD in this area imf members\\u0027 quotas and voting power
