Higgs Found

Cern press release

Both experiments observe a new particle in the mass region around 125-126 GeV.
“We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage,” said ATLAS experiment spokesperson Fabiola Gianotti, “but a little more time is needed to prepare these results for publication.”
"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,”

I watched the live webcast of the CERN update seminar.   Peter Higgs was sitting there and was noticeably moved when Fabiola Gianotti announced the final results from the Atlas detector.  The largest machine in the world, operated by over 3,000 scientists and engineers with collaborators all over the world.  This was a global project. Go Physics!!
