But it looks like someone jumped the gun.
A video confirming the discovering of the new particle was accidentally posted on CERN's website for a brief time this morning, Tom Chivers of The Telegraph reports.
In the video, Joe Incandela, the CMS spokesperson says:
We've observed a new particle. We have quite strong evidence that there's something there. Its properties are still going to take us a little bit of time. But we can see that it decays to two photons, for example, which tells us it's a boson, it's a particle with integer spin. And we know its mass is roughly 100 times the mass of the proton. And this is very significant. This is the most massive such particle that exists, if we confirm all of this, which I think we will."
