What an exciting day to be a particle physicist!
The observation of the Higgs boson was announced today at CERN.
This particular particle has been long sought after, but searches at LEP, the Tevatron, and other facilities have failed to produce conclusive evidence for its existence. Today's announcement is the result of a lot of hard work from a very large number of people, including the ones whose search came up short.
Since the Higgs has been missing for so long, we kind of know already a lot about it. It's like putting together a puzzle. Even if you are missing a piece, you know exactly what it looks like based on the pieces that you do have. There are other blogs, who can explain much better what we think it looks like, for example Flip Tanedo's.
I'm an experimentalist. What we need to do now is measure the Higgs back and forth, inside and out. We need to look at it, and understand if it's really the last missing piece in our puzzle. There are some other very important questions, none of which can really be answered by our current flavor of puzzle, the Standard Model.
Personally, I hope this discovery opens the door to even more questions.
