The H boson gateway to physics beyond the Standard Model

In 2012, a scalar particle has been discovered at the LHC (CERN). As of today, its properties match those of the Brout-Englert-Higgs (H) boson of the standard model, the current theory of fundamental interactions.

The overarching objective of this project, lead by a collaboration of theorists and experimentalists, is to use the H boson as a probe of still largely unexplored territories beyond the standard model. First, it aims at more precisely determining the H boson couplings within the standard model, including its self-coupling. Concurrently, researchers will look for new scalar particles, possible siblings of the H boson. Second, they will focus on a special feature of the H boson, that of providing a gateway to a whole new world of hidden particles and interactions, an exploration which may shed light on the dark matter and neutrino mysteries.

The project is a collaboration between UCL, VUB, Universiteit Gent, Universiteit Antwerpen and teams from ULB Faculty of Sciences : Riccardo Argurio (Theoretical and mathematical physics) - Barbara Clerbaux, Laurent Favart & Pascal Vanlaer (IIHE) - Thomas Hambye & Michel Tytgat (Theoretical Physics).
