At the start of July, scientists announced that they’d discovered what they strongly believed to be the Higgs Boson, a particle that’s believed to be the key to unifying the standard and quantum models of physics. Now, after a handful more experiments, they’re even more certain that they’ve finally got it. More »
Les Horribles Cernettes got their photo published in an HTML page 20 years ago. It was the first photo in the history of the web, which makes them the first music band in the history of the web too. Here’s how their song Collider sounds. More »
The discovery of the Higgs boson is kind of a big deal. Stephen Hawking certainly thinks so: he says it should net Peter Higgs, the scientist after which the particle is named, a Nobel prize. But it’s not all good news, because the result has lost him $100. More »
At a meeting held at CERN this morning, scientists presented the latest results from the search for the long-sought Higgs particle. After 30 years of research and $9 billion of investment, they’ve changed the face of physics forever: they’ve found the Higgs boson. More »
Physics’ big announcement had more in common with a leaky product launch than the serious business of re-writing the science books. But slack asset management aside, it’s official: a new boson has been observed with a standard deviation of 5 (confidence of 99.9%). The highly anticipated announcement came this morning direct from CERN’s press conference (via ICHEP in Melbourne,) and is the result of an intense, ongoing search for the elusive particle. The observation is of a boson particle with a mass of 125.3 ± 0.6 GeV, at a significance of 4.9 sigma. Joe Incandela — giving the presentation — said that this is “In agreement with the standard model at 95% confidence range.” The boson is the heaviest ever found, and although this is still a preliminary result, it’s by far the strongest case yet for the existence of the elusive Higgs.
The sought-after particle is essential for supporting the current understanding of sub-atomic world, and its bearing on nuclear, and electromagnetic interactions. The next stage will be to determine the exact characteristics of the new particle and whether it matches the expectations of the Higgs, or is it in fact something more “exotic.” This part will take much more time, but for now, a (very) small, but important piece of the puzzle has been found.
Update: We’re sure you’ve got many questions, and CERN apparently anticipated this. Check out the more coverage link for a helpful FAQ about everything Higgs.

We had a false alarm over the possible discovery of the theory-unifying Higgs boson last year, but a bit of poking and prodding in subsequent months may well have given us much more definitive evidence of the elusive particle. According to some rare rumors emerging from Nature, both CERN’s ATLAS and CMS detectors have seen particle decay signals suggesting the existence of Higgs to within a 4.5 to 5 sigma level of proof — in other words, very nearly concrete evidence. That’s not quite the 5-plus needed to settle the matter, but it’s to a much higher level of certainty than before. As if to add fuel to the fire, ScienceNews even located a briefly posted, CERN-made video (sadly, since pulled) saying bluntly that the CMS team had “observed a new particle.”
Whether or not there’s any substance is another matter. Nature hears that scientists are supposedly still working out what to say at an event on Wednesday, while CERN has made the slightly odd claim to ScienceNews that the yanked video is just one of several pre-recorded segments made to cover possible outcomes — you know, in that “Dewey defeats Truman” sort of way. Unless the scientists have to go back to the drawing board, though, the focus from now on may be more on learning how Higgs behaves than its very existence. Any significant truth could see researchers proving the validity of the standard model of physics just as we’re firing up our Independence Day barbecues.
