Abstract
We describe a formalism for calculating electroweak Sudakov logarithms in t he Coulomb gauge. This formalism is applicable to arbitrary electroweak pro cesses. For illustration we focus on the specific reactions e(+)e(-) --> f (f) over bar and e(+)e(-) --> WT+WT-, WL+WL-, which contain all the salient details of dealing with the various types of particles. We discuss an expl icit two-loop calculation and have a critical look at the (non-)exponentiat ion and factorisation properties of the Sudakov logarithms in the Standard Model.
