Next-to-leading order QCD corrections to W^{+}W^{+}jj production in vector-boson fusion at the LHC


Denner, A; Hošeková, L; Kallweit, S (2012). Next-to-leading order QCD corrections to W^{+}W^{+}jj production in vector-boson fusion at the LHC. Physical Review D (Particles, Fields, Gravitation and Cosmology), 86(11):1-30.

Abstract

We present a next-to-leading order QCD calculation for e+νeμ+νμjj production in vector-boson fusion, i.e., the scattering of two positively charged W bosons at the LHC. We include the complete set of electroweak leading order diagrams for the six-particle final state and quantitatively assess the size of the s-channel and interference contributions in vector-boson fusion kinematics. The calculation uses the complex-mass scheme to describe the W-boson resonances and is implemented into a flexible Monte Carlo generator. Using a dynamical scale based on the transverse momenta of the jets, the QCD corrections stay below about 10% for all considered observables, while the residual scale dependence is at the level of 1%.
