Discovering the Higgs boson in 2012 was only the start. Physicists immediately began measuring its properties, an investigation that is still ongoing as they try to unravel if the Higgs mechanism is realized in nature as predicted by the Standard Model of particle physics. Earlier this spring, researchers at CERN's ATLAS Experiment announced they had measured the Higgs boson in its decays to W bosons. W bosons are particularly interesting in this context, as the properties of their self-interaction (vector boson scattering) gave credibility to the mechanism that predicted the Higgs boson.
