Yearbook 2021: Novel approach to understand the Higgs particle's mass
The discovery of a Higgs-like particle at the CERN Large Hadron Collider (LHC) represents one of the biggest findings of the last decades. Notwithstanding, its small mass is in conflict with general physical arguments. Most of the models that can address this issue, by considering the Higgs particle to be composed of more fundamental states, however predict light partner particles of the top quark, which have not been found yet at the LHC. A novel mechanism of symmetry breaking could resolve this tension.
