Description
To match the expected experimental precision at future linear colliders, improved theoretical predictions beyond next-to-leading order are required. At the anticipated energy scale of ÷s =1 TeV the electroweak virtual corrections are strongly enhanced by collinear-soft Sudakov logarithms of the form log 2(s/M 2), with M being the generic mass scale of the W and Z bosons. By choosing an appropriate gauge, we have developed a formalism to calculate such corrections for arbitrary electroweak processes.
