Using SCET to calculate electroweak corrections in gauge boson production

Understand

We extend an effective theory framework developped in Refs.

• [1,2] to sum electroweak Sudakov 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 Delta regulator, which respects soft-collinear factorization.
