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 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 pp -> W+ -> l(+)nu and selected kinematic distributions in this process are presented.

Automated summary

Mixed QCD-electroweak corrections to fully differential production of an on-shell W boson, including decays of W bosons to lepton pairs in the leading order approximation, are computed analytically for arbitrary electroweak gauge boson masses. Analytic results for integrated subtraction terms are obtained within a soft-collinear subtraction scheme tailored to handle the structural simplicity of infrared singularities of mixed QCD-electroweak contributions, with numerical results presented for mixed corrections to the fiducial cross section of pp -> W+ -> l(+)nu and selected kinematic distributions in this process.
