And a nice way to start the Christmas party season at CERN.

http://www.guardian.co.uk/science/blog/ ... c-findings

"The runup to Christmas looks exciting for the Large Hadron Collider at Cern near Geneva. Staff at the laboratory have arranged a special seminar on Tuesday 13 December at which the latest results in the search for the Higgs boson will be made public. The presentation is due to happen directly after the lab's scientific policy committee has convened one of its regular meetings behind closed doors."

And rumors we hear rumors.

http://blog.vixra.org/2011/12/02/higgs- ... o-125-gev/

"A rumour that reached our comment section suggests that a signal for the Higgs boson has been seen at 125 GeV with 2-3 sigma significance."

Oh but we do love the rumors ;) that is what keeps it exciting hehe.

Judging from the rumors it sounds like they haven't found a thing. They have narrowed the region where the Higgs could be hiding, or one could say that the chances of finding it have become slim.

Aside from setting records it seems that the LHC is starting to fall into the category of the Michelson–Morley experiment:
"After all this thought and preparation, the experiment became what might be called the most famous failed experiment to date."

Not sure I entirely agree that they've found nothing.

I guess its a sign-off conference for the winter period closure, and an "I hope to see y'all again next year"-motivational-speech that we will get to see, talking about the misty 2,5 - 3 sigma results.

What will happen with Peter Higgs and his boson if they don't find it by the summer of next year, same thing as Ivan, quietly leaving the scene ...

Sorry for being a bit sinister, but it might be my last chance ever to speculate on such things :mrgreen:

Well I'm a bit uncertain about the exclusions. How can they exclude areas at "95% certainty" ? That's a way lower level of certainty than they require for discovery. Why the large disparity between the two numbers ? Presumably something I'm not understanding about the statistics.

The numbers:
the Atlas team reported a 2.3 sigma bump in their data that could be a Higgs boson weighing 126GeV, while the CMS team reported a 1.9 sigma Higgs signal at a mass of around 124GeV.

Too small or big enough to be a worthy cliffhanger?

I just checked Ethan Siegel's blog, Starts with a Bang and he's pretty confident that they are on to something:

It still isn't good enough to claim discovery, but it's striking enough that if you asked me to bet, I'd bet you even money that they confirm a Higgs somewhere around 126 GeV by the end of 2013.

ATLAS asked for 20 fb-1 in order to confirm (that's how much data they would need, if the Higgs is really around 125GeV, to get a 5 sigma discovery) which is at the optimistic end of the 2012 run.

I found the recording of the webcast where the presentations about the Higgs boson by the ATLAS and CMS experiments were given of 13 december.
