Electroweak Sudakov Corrections using Effective Field Theory
arXiv:0709.2377 · doi:10.1103/PhysRevLett.100.021802
Abstract
Electroweak Sudakov corrections of the form alpha^n log^m s/M_{W,Z}^2 are summed using renormalization group evolution in soft-collinear effective theory (SCET). Results are given for the scalar, vector and tensor form-factors for fermion and scalar particles. The formalism for including massive gauge bosons in SCET is developed.
