In this article we present an event generator based on the Monte Carlo program Powheg in combination with the matrix-element generator Recola. We apply it to compute NLO electroweak corrections to same-sign W-boson scattering, which have been shown to be large at the LHC. The event generator allows for the generation of unweighted events including the effect of the NLO electroweak corrections matched to a QED parton shower and interfaced to a QCD parton shower. In view of the expected experimental precision of future measurements, the use of such a tool will be indispensable.

    hep-ph 2026-02 conditional novelty 7.0

    A resonance-aware MC@NLO matching procedure preserves top-antitop line shapes when NLO QCD predictions for off-shell ttbar production at e+e− colliders are showered with Pythia8.

    hep-ph 2026-06 unverdicted novelty 4.0

    NLO QCD and EW corrections computed for semileptonic vector-boson scattering in two fiducial regions at the LHC.

  3. Precision calculations for electroweak multi-boson processes

    hep-ph 2026-04 unverdicted novelty 2.0

    Electroweak corrections reach about -16% for like-sign WW scattering and -7% for triple-W production at the LHC, even for integrated cross sections, and the paper discusses approximations to full off-shell calculations.
