$W^{+}{W}^{-}$ production at the LHC: NLO QCD corrections to the loop-induced gluon fusion channel

Abstract

We compute the NLO QCD corrections to the loop-induced gluon fusion contribution in $W^{+}{W}^{-}$ production at the LHC. We consider the full leptonic process $pp\to {\ell }^{+}{\ell }^{\prime -}{\nu }_{\ell }{\bar{\nu }}_{{\ell }^{\prime }}+X$, by including resonant and non-resonant diagrams, spin correlations and off-shell effects. Quark-gluon partonic channels are included for the first time in the calculation, and our results are combined with NNLO predictions to the quark annihilation channel at the fully differential level. The computed corrections, which are formally of $\mathcal{O}({\alpha }_{\mathrm{S}}^3)$, increase the NNLO cross section by only about 2%, but have an impact on the shapes of kinematical distributions, in part due to the jet veto, which is usually applied to reduce the top-quark background. Our results, supplemented with NLO EW effects, provide the most advanced fixed-order predictions available to date for this process, and are compared with differential ATLAS data at $\sqrt{s}=$ 13 TeV.
