COMETA Colloquium: Tim Cohen (CERN, University of Oregon)

Monday 20 Apr 2026, 14:00 → 16:00 Europe/Zurich

This event is organised by the COMETA COST Action, a EU-funded networking initiative that promotes knowledge sharing and cooperation across the theory, experiment, and ML communities, with the aim of improving the measurement and interpretation of multiboson processes at the LHC.

1 The Geometry of Particle Physics

In this colloquium, I will explain that there is a hidden geometry that exists within the Standard Model of Particle Physics. This is due to the modern interpretation of the Standard Model as a so-called Effective Field Theory. I will review this fundamental paradigm and will explain the deep connection between Effective Field Theories and the ideas of Geometry as they are utilized in general relativity. This geometric perspective provides key insights into the interpretation of beyond the Standard Model physics, and opens up new and exciting directions for future exploration.

Tim Cohen is a CERN staff member (on leave from an Associate Professor position at the University of Oregon, USA). He got his PhD from the University of Michigan, USA in 2011. He has broad interests in beyond the Standard Model theory, ranging from theory and application of Effective Field Theories to understanding the nature of dark matter to finding new probes of dark sector strong dynamics at the LHC.
