In particle physics-speak, the Higgs appears to have a mass of 125 GeV (giga­electronvolts).
The upshot is that if this is proven, one of physics' bedrock theories -- the Standard Model -- is holding steady. If the Higgs does exist with this mass, then perhaps some more tricky Universal mysteries can be resolved.
If the insider-trading-like rumors are substantiated, the ATLAS detection has been measured to a 3.5-sigma certainty and the CMS result has been measured to a 2.5-sigma certainty. All these "sigmas" may not mean much, but they are a measure of the statistical certainty of a given result.
In an earlier Discovery News article Sean Carroll, senior research associate in the Department of Physics at Caltech, shed some light on what this means.
"Three-sigma events happen occasionally, especially when you look at a lot of data," he said. "But it could be real."
At 3.5-sigma, the ATLAS measurement has a 0.1 percent chance of being a "random fluke." The 2.5-sigma result has a 1 percent chance of being a fluke. With those odds, it's little wonder there's some excitement stirring. However, particle physicists are meticulous about their statistics before going public with any discovery.
Personally, I think it would have been more fun had it never been found...or confirmed to not exist. Still, very exciting news.
