We analyze the result + in the context of  hard and infrared evolution equations and establish + a matching ​ procedure which relates the  theories with and without + mass gap setting ​ the stage for the complete calculation of the  dominant + ​two-loop corrections to electroweak processes at high energy. + ​ + |**Bernd Feucht, Johann H.
