All Signs Point to Higgs Boson, but Still Waiting for Scientific Certainty - NYTimes.com - 1 views

physicists admit that it will take more work and analysis before they will have the cold numbers that clinch the case that the new particle announced on July 4 last year is in fact the exact boson first predicted by Peter Higgs and others in 1964 to be the arbiter of mass and cosmic diversity

What happened in the first instant of the Big Bang? What happens at the middle of a black hole where matter and time blink in or out of existence? What is the dark matter whose gravitational influence, astronomers say, shapes the structures of galaxies, or the dark energy that is forcing the universe apart? Why is the universe full of matter but not antimatter? And what, finally, is the fate of the universe? These are all questions that the Standard Model, the vanilla-sounding set of equations that ruled physics for the last half century, does not answer

Some of them could be answered by the unproven theory called supersymmetry, which among other things is needed to explain why whatever mass the Higgs has is low enough to be discovered in the first place and not almost infinite. It predicts a whole new population of elementary particles — called superpartners to the particles physicists already know about — one of which could be the dark matter that pervades the universe. If such particles exist, they would affect the rate at which Higgs bosons decay into other particles, but the CERN teams have yet to record what they consider a convincing deviation from the Standard Model predictions for those decays. Supersymmetry is still at best a beautiful idea.
