The spokesperson for the other experiment was equally clear and equally cautious. "The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found,” said CMS experiment spokesperson Joe Incandela.“The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks."
There is no doubt that a new boson has been found, with Higgs like properties. The magic number 5 sigma is found by combining more than one decay mode, which some people cavil at. This may be the Standard model Higgs, or it may have properties beyond the Standard model. However, the bottom line is exactly what the Director General of CERN said. “We have reached a milestone in our understanding of nature,” said CERN Director General Rolf Heuer. “The discovery of a particle consistent with the Higgs boson opens the way to more detailed studies, requiring larger statistics, which will pin down the new particle’s properties, and is likely to shed light on other mysteries of our universe.”

So there were fireworks on the 4th of July, after all!
Tailpiece: A Higgs boson walks into a bar, and slaps a large denomination Euro note on the counter. `A big one', it says, ' I've been discovered'. The bar tender says, `Are you the one they've been looking for?' `Who cares? ' sniffs the boson. `If I'm not the one, it's even better'.
@ Rahul Siddharthan: Take a look at this link We blogged a lot on the Higgs last year, and a great deal of the story is here, jokes and all.
