摘要
The two-loop Sudakov form factor is computed in a U(1) model with a massive gauge boson and a model with mass gap. 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.
