The Higgs boson was discovered by the ATLAS and CMS Collaborations at CERN’s Large Hadron Collider (LHC) in 2012 through its decays into pairs of photons, W bosons and Z bosons. Since then, physicists at these experiments have gained great insight into the properties of the Higgs boson through the study of its different production and decay processes. Decays to pairs of tau leptons and bottom quarks were established, as was the coupling to top quarks. However, the question remains whether the Higgs boson may also interact with yet-unknown particles or forces.
