More Evidence to Support Discovery of the Higgs Boson
Despite what many news media sources may have reported, the particle discovered at CERN in 2012 may not have been the sought for Higgs boson that provides elementary particles with mass. Many indicators did suggest that it was, but more work was required to confirm it. As it is more research is still required, but many researchers, including those at Kansas State University have completed a study to further support the hopes for what was found two years ago.
For decades scientists have known of a critical flaw to our understanding of elementary particles. While many of their properties could be predicted mathematically, the theories involved could explain where their mass came from. In 1964 the Higgs boson was suggested as the source, by giving mass to those particles that interact with them. Since then we have been working out predictions for its properties and ways to find it, until 2012 when we believe we did. Some questions still remained though, such as what the particle decays into. According to the theory, the boson would decay into fermions, like the particles that make up all normal matter. Bosons, for comparison, are what mediate interactions between elementary particles. Now teams of researchers are publishing their findings that the discovered particle should indeed decay into fermions, just as predicted of the Higgs boson.
By giving elementary particles mass, the Higgs boson would solve many mysteries of the Universe, but at the same time would open up many more. As it is now, particle physics is explained with the Standard Model, but we know it fails to explain everything. Yet, it still does the best job of other theories, with the discovery of the Higgs boson potentially leading to that new, better model.
