Using SCET to calculate electroweak corrections in gauge boson production

Abstract

We extend an effective theory framework developped in Refs. [1, 2] to sum electroweak Su-dakov logarithms in high energy processes to also include massive gauge bosons in the final state. The calculations require an additional regulator on top of dimensional regularization to tame the collinear singularities. We propose to use the ∆ regulator, which… (More)
