Matching in logarithmically accurate parton showers

by Dr Alexander Karlberg (CERN)

Friday 26 May 2023, 14:00 → 16:00 Europe/Zurich

4/3-006 - TH Conference Room (CERN)

Parton showers are ubiquitous theoretical tools in collider physics providing a crucial link between theory and experiment. In this talk I will give a general introduction to parton showers and review recent developments in understanding and improving their accuracy - all within the context of the PanScales collaboration. In the second half of the talk I will discuss how to match logarithmically accurate parton showers to fixed-order matrix elements, without spoiling the logarithmic accuracy. I will in particular discuss subtleties which give rise to spurious super-leading logarithms if not treated correctly.
