COMETA workshop on vector-boson polarisations

23 Sept 2024, 09:00 → 24 Sept 2024, 18:00 Europe/Paris

Amphi 3 (Maison de la Recherche et de la Valorisation, Toulouse (France))

Giovanni Pelliccioli (Max-Planck-Institut für Physik), Ilaria Brivio (University & INFN Bologna), Joany Manjarres (Laboratoire des 2 Infinis - Toulouse, CNRS / Univ. Paul Sabatier (FR)), Ramona Groeber (Università di Padova and INFN, Sezione di Padova)

The focus of this workshop is to review the state-of-the-art in polarisation modelling and measurements, discussing the required improvements, with an eye on machine-learning-based techniques to discriminate amongst vector-boson polarisations.

It is hosted at the University of Toulouse in the two days preceding the Multi-Boson Interaction 2024 conference (also hosted in Toulouse).

This workshop is organised by COMETA COST Action (CA22130).
