Today’s Higgs Results
(200 words excerpt, click title or image to see full post)

The discussion after the talks is going on at CERN now, and the results that were presented agree well with what was posted here over the past week or so. This looks a lot like a Higgs near 125 GeV. Hiccups in the streaming make it difficult to impossible to follow the discussion. Caught Heuer at the end urging caution: “intriguing hints”. This looks to me like a lot more than “intriguing hints”: it’s about what you would expect if a Higgs was there at 125 GeV, highly unlikely to see if there is no Higgs there.
The ATLAS results are here
Higgs to gamma gamma: 2.8 sigma bump at 126 GeV
Higgs to ZZ to 4l: 2.1 sigma (3 events near 125 GeV)
Higgs to WW to l nu l nu: Data not fully analyzed, 1.4 sigma excess at 126 GeV
Combination: 3.6 sigma excess at 126 GeV.
The CMS results are here

Higgs to gamma gamma: 2.34 sigma bump at 123.5 GeV.
Higgs to ZZ to 4l: 2 events seen near 126 GeV (expect .5 background)
Combination: 2.4 sigma excess at 124 GeV.
I see Tommaso Dorigo is posting a detailed analysis here under the title “Firm Evidence ...
