Description

We present a computation of inclusive diboson production in the $W^{\pm} Z$ channel at the Large Hadron Collider (LHC), incorporating leptonic decays of the gauge bosons and considering intermediate gauge bosons with definite polarization states. The analysis includes contributions from the Standard Model effective field theory (SMEFT) and is carried out at next-to-leading order (NLO) accuracy in QCD, matched to a parton-shower simulation.
Our implementation allows for the selection of specific helicity configurations, both in the Standard Model and in the presence of dimension-six operators inducing anomalous triple gauge boson couplings.
