We study the polarisation of gauge bosons produced at the LHC. Polarisation effects for W bosons manifest themselves in the angular distributions of the lepton and in the distributions of lepton transverse momentum and missing transverse energy. The distributions also depend on the selection cuts, with kinematic effects competing with polarisation effects. The polarisation is discussed for a range of different processes producing W bosons: W+jets, W from top (single and pair) production, W pair production and W production in association with a Z or Higgs boson. The relative contributions of the different polarisation states varies from process to process, reflecting the dynamics of the underlying hard-scattering process. We also present results for the polarisation of the Z boson produced in association with QCD jets at the LHC, and comment on the differences between W and Z production.

  1. The cleanest of them all: NLO electroweak corrections to vector-boson scattering into doubly polarised ZZ pairs at the LHC

    hep-ph 2026-07 unverdicted novelty 7.0

    First NLO electroweak corrections to doubly polarised ZZ vector-boson scattering at the LHC computed in the double-pole approximation with factorisable real and virtual corrections.

  2. Polarization interference in exclusive $V+$jets at all orders in $\alpha_s$

    hep-ph 2026-06 unverdicted novelty 7.0

    Polarization interference in γ*→ℓ+ℓ− vanishes after lepton integration in exclusive V+jets at all α_s orders, with softened cancellations for W/Z due to parity violation and a formula for fiducial cuts.
