Hello; I was just wondering what would happen if the Higgs boson particle did exist or did not exist. If we conclude that it does not exist, what would happen to the standard model of particle physics, and the equation that describes how particles interact with each other? Because if the Higgs boson does not exist, what happens to this equation? Does it become obsolete? My other question is what evidence do we have for the existence of the Higgs boson and the Higgs field? I have heard that they will be making another attempt to find it at CERN next month. Thanks.
