Description
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 an automated matching of a QED parton shower with NLO EW calculations for processes at a future lepton collider. I will introduce the MC@NLO method, then outline the challenges inherent in initial-state lepton showering and our solutions. After showing that our implementation is independent of its technical parameters, I will present results for the highly relevant process $e^+ e^- \to ZH$ at FCC-ee energies.
