...The latest results from the ATLAS detector at the LHC suggest that when we look at its decay into two photons, we find that the new boson's mass is about 3 gigaelectronvolts greater than when calculated from its decay into particles called Z bosons.
Albert De Roeck, one of the key Higgs hunters at ATLAS's sibling detector, CMS, finds this puzzling. "The results are barely consistent," he says...
The ATLAS team also announced new results from analysing the Higgs boson's rate of decay into pairs of photons. The standard model of particle physics predicts exactly how often this should happen. Intriguingly, when early hints of a new particle were upgraded to a "discovery" in July, it was doing that more often than the standard model says it should. But there was not enough data to say whether this was a fluke.
If the Higgs really decays into photons at too fast a rate, it would offer some clues as to where to look for new physics that might explain mysteries like dark matter, gravity and the dearth of antimatter in the universe.
Today, physicists announced that the excess has not gone away -- but it also does not look much more likely to be a genuine event, even though physicists have now seen twice the number of decays.

The latest results from the Atlas experiment indicate that there may be two different Higgs bosons -- one that weighs 123.5 GeV (in blue) and another that's 126.6 GeV (in red). [Have Scientists Found 2 Different Higgs Bosons?]
1.21 jigawatts, Marty
And that’s why CERN has not yet invented time travel. They clearly need more power.
While I greatly appreciate the preliminary Atlas/maps for 2011 and 2012, detailing Mr. Boson’s probable home location, does it or does it not have a registered weapon there?
No sign of the Higgs boson

At last we have a crude drawing of Ms. Higgs bosom but I feel a little voyeuristic looking at it.
Where’s Moe Howard when I need him?
If you know the position of the registered weapon you’ll never know the speed of it and vice versa!
In the beginning God created the heavens and the earth.......
Moar research monies PLZ...
Isn`t the boson in Germany?
Didn`t I read somewhere the boson got re-introduced to Germany after 1,000 years?
Am I going to Hell if I ask how?
Until last week I thought the Higgs Boson served under the command of Captain Higgs.
Thanks for the ping. Happy New Year!
