Parton showers are an essential feature of event generation that provide a numerical resummation of the large logarithms that enhance soft and collinear radiation. Matching them to higher order calculations requires careful treatment in order to avoid double-counting real radiation and preserve fixed order accuracy through matching algorithms such as MC@NLO. As we approach HL-LHC, there is a...

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...

It has recently been proposed that collider events can be equipped with a metric, the Energy Mover’s Distance (EMD), which allows one to rephrase multiple aspects of jet physics in a geometric language. Further, the EMD can be exploited to define new observables that measure the distance between a given event and an idealised one. For instance, event isotropy quantifies the resemblance of an...

We present new Monte-Carlo tools for precision phenomenology in longitudinally polarized scattering processes, providing next-to-leading order QCD predictions matched to parton showers (NLO+PS) within the POWHEG BOX framework for di-jet production in polarized proton–proton collisions and polarized deep inelastic scattering. The generators are designed to deliver fully differential predictions...
