We present the calculation of next-to-leading-order electroweak correctionsto W-boson pair production at the LHC, taking off-shell effects of the W bosonsand their leptonic decays into account in the framework of the so-calleddouble-pole approximation. In detail, the lowest-order cross section and thephotonic bremsstrahlung are based on full matrix elements with four-fermionfinal states, but the virtual one-loop corrections are approximated by theleading contributions of a systematic expansion about the resonance poles ofthe two W bosons. This expansion classifies the virtual corrections intofactorizable and non-factorizable corrections, the calculation of which isdescribed in detail. Corrections induced by photons in the initial state, i.e.photon-photon and quark-photon collision channels, are included and based oncomplete matrix elements as well. Our numerical results, which are presentedfor realistic acceptance cuts applied to the W-boson decay products,qualitatively confirm recent results obtained for on-shell W bosons and revealelectroweak corrections of the size of tens of percent in the TeV range oftransverse momenta and invariant masses. In general, photon-photon andquark-photon induced contributions amount to 5-10% of the full differentialresult. Compared to previous predictions based on stable W bosons electroweakcorrections, however, can change by several percent because of realistic cutson the W-boson decay products and corrections to the decays.
