When I read articles declaring the discovery of the Higgs Boson I come across a note that the research teams are NOT identifying this particle as the Higgs Boson.
“However, the teams, which included hundreds of Britons, stopped short of declaring it the Higgs boson, saying more work is needed to confirm its properties.” Full Article
“They are stopping just short of saying that they have discovered the Higgs boson, which has been postulated to explain why matter has mass and why mass plus gravity equals weight. They are saying only that they have discovered a new subatomic particle that is largely consistent with the predicted Higgs particle.” Full Article
This one at least presents what the scientists are saying; that the “new boson “sings and dances like” the theoretical particle.” Later in the same article “The collider will provide more data later this year, giving scientists a more complete picture of the observed new particle. Researchers will try to determine whether it is a Higgs boson, the particle predicted by the Standard Model.”
So I understand everyone watching the experiment is pretty sure, this is the Higgs Boson!, however, if the scientists doing the work are not declaring this the Higgs Boson quite yet, why is everyone else?
