Colourless processes at EW NLO+Parton Shower

• Lois Flower

Room: OLL/337 NLO parton shower matching has been one of the triumphs of QCD research and Monte Carlo development in the past 20 years. With high-precision future electron-positron colliders planned, however, there is an urgent need for theory advances in QED and the electroweak sector. In this talk I will present the first QED parton shower matched to NLO EW using an automated, process-independent method. I will briefly introduce the MC@NLO method, then outline the challenges inherent in initial-state lepton parton showering and our solutions. After showing that our implementation is independent of the technical parameters it depends on, I will present results for the highly relevant process $e^+ e^- \to ZH$ at FCC-ee energies. Finally, I'll discuss the next steps and future plans for this method.
