TL;DR
This paper calculates next-to-leading order QCD corrections for WWZ production with leptonic decays at the LHC, providing a flexible Monte Carlo tool to improve the accuracy of multi-lepton event predictions.
Contribution
It presents the first full NLO QCD correction calculations for the complete six-lepton final state in WWZ production, implemented in a versatile Monte Carlo program.
Findings
QCD corrections significantly affect WWZ production cross sections.
The Monte Carlo program allows for detailed distribution and cut analyses.
Results enhance precision in multi-lepton background estimates.
Abstract
Multi-lepton signatures appear in many new physics searches at the Large Hadron Collider. We here consider WWZ production with subsequent leptonic decay of the three vector bosons as a SM source of multi-lepton events. We have calculated the next-to-leading order QCD corrections for the full lepton production cross sections in hadronic collisions. Results have been implemented in the form of a flexible parton-level Monte-Carlo program which allows to calculate the QCD corrections for arbitrary distributions and acceptance cuts.
