Abstract

We compute mixed QCD-electroweak corrections to the fully-differential production of an on-shell WW boson. Decays of WW bosons to lepton pairs are included in the leading order approximation. The required two-loop virtual corrections are computed analytically for arbitrary values of the electroweak gauge boson masses. Analytic results for integrated subtraction terms are obtained within a soft-collinear subtraction scheme optimized to accommodate the structural simplicity of infra-red singularities of mixed QCD-electroweak contributions. Numerical results for mixed corrections to the fiducial cross section of ppW+l+νpp \to W^+ \to l^+ \nu and selected kinematic distributions in this process are presented.
