NLO EW corrections to polarised W${}^{+}$W${}^{-}$ production and decay at the LHC

Abstract

In this letter we present results for next-to-leading-order electroweak corrections to doubly polarised W${}^{+}$W${}^{-}$ production at the LHC in the fully leptonic decay channel. We model the production and the decay of two polarised W bosons in the double-pole approximation, including factorisable real and virtual electroweak corrections, and separating polarisation states at amplitude level. We obtain integrated and differential predictions for polarised signals in a realistic fiducial setup.
