Hints of Higgs? Maybe…

The big science news today is the announcement of the latest results from the Large Hadron Collider”s search for the elusive Higgs boson, and while the results are far from conclusive so far, they’re actually mildly encouraging.  Two independent detectors got pretty much consistent results suggesting the possibility of a particle with a mass somewhere around 125 GeV.  (That’s giga electron volts — since E=mc^2, physicists measure particle mass in units of energy.)

Here’s the New York Times piece on the news, including links to the raw data published on a site called TWiki (whose motto is probably not “bidi-bidi-bidi”).  Here’s a more detailed article from New Scientist.  However, the most useful link I’ve come across is this Higgs FAQ from the blog of particle physicist Matt Strassler.  I’ve never quite understood what all this Higgs field/particle business was all about until recently, but I’m starting to get a handle on it now.  The FAQ does a good job of explaining the Higgs field and its role, and why not finding the Higgs particle would be just as intriguing and useful a result as finding it.  (Because the particle isn’t the key, it’s just the simplest and only known way of detecting the Higgs field, which is the thing that’s actually important.  And if there were no particle, it would just mean the field is different than the simplest model suggests, or that it works in a different way, not that it didn’t exist.)

So nothing conclusive today, but interesting hints that will be pursued further.  Apparently they’ll be able to confirm or deny this evidence by next summer, and if it doesn’t pan out, they’ll try something else when the LHC reaches full power in 2015.
