Mixed QCD-electroweak corrections to W -boson production in hadron collisions

We compute mixed QCD-electroweak corrections to the fully differential production of an on-shell W boson. Decays of W 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 ga...

Zusammenfassung:We compute mixed QCD-electroweak corrections to the fully differential production of an on-shell W boson. Decays of W 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 infrared singularities of mixed QCD-electroweak contributions. Numerical results for mixed corrections to the fiducial cross section of p p → W+ → l+ν and selected kinematic distributions in this process are presented.
