Back in December, CERN physicists announced that they had probably spotted the long-awaited Higgs boson - at least, there was a 99.7% chance that they had. Now they've examined the data again, and it's looking even better for the Higgs.

The December results came from the Large Hadron Collider's two independent experiments, ATLAS and CMS. While both potential sightings were promising, neither met the accepted standard for an actual discovery, which is known as a 5-sigma result. A 5-sigma result means there's only about a 1 in a million chance that the finding is the result of error or random fluctuation in the data.

All the individual results hovered around the 2-sigma level, which together combined for a joint 3-sigma result. That meant there was only a 0.3% chance the results were in error. That's impressive, but it's well short of 1 in a million. Well, we can now close that gap quite a bit, as physicists on the Compact Muon Solenoid (CMS) have reexamined their original results and upgraded their Higgs signal from 2.5-sigma to 3.1-sigma.

When combined with the ATLAS results, that gets us all the way to 4.3-sigma, which means there's a 99.996% of the Higgs really being there in the data. That's still short of the 5-sigma standard, but it's a lot closer than where we thought we were in December. With the Large Hadron Collider due to go back online this spring, there's a very real chance that 2012 could end up being the year of the Higgs.
