Boson decays refer to the process by which boson particles, which are a class of elementary particles that include photons, W and Z bosons, and the Higgs boson, decay into other particles. This process is governed by the laws of quantum mechanics and the Standard Model of particle physics. Studying boson decays can provide crucial insights into the properties and interactions of these fundamental particles, as well as potentially reveal new physics beyond the Standard Model. Researchers conduct experiments at particle accelerators such as the Large Hadron Collider to study these decays and better understand the behavior of bosons.
