NLO QCD corrections to $W^\pm Z\gamma$ production with leptonic decays

Understand

We present a computation of the O(alpha_s) QCD corrections to W^\pm Z \gamma production at the Large Hadron Collider.

• The photon is considered as real, and we include full leptonic decays for the W and Z bosons.
• Based on the structure of the VBFNLO program package, we obtain numerical results through a fully flexible Monte Carlo program, which allows to implement general cuts and distributions of the final-state particles.
• The NLO QCD corrections are sizable and strongly exceed the theory error obtained by a scale variation of the leading-order result.
