The Higgs Boson search at the LHC


TopCat®

It has been announced that the scientists believe they are very close to discovering the 'holy grail' of particles known as the Higgs Boson. Further tests on the 'unknown' they have found are needed before they can be certain it is the missing link.

Reading the numerous comments at the bottom of the story page at the BBC website - story here- a particular response caught my eye. It comes from a 'Jamsie' at comment 415, which for possible copyright reasons I won't post here.

Just out of interest, I wondered if you would agree with the response Jamsie made. I certainly do. TC.

"As I understand it, they are sure they've found it but they haven't finished all the checks to see if they've made a mistake."

They were statistically re-analysing the vast amount of data to see if the results were a coincidence or not. Prior to yesterdays announcement, the results were only significant at the 3-sigma level (i.e. the sort of probability equivalent to getting the same result when tossing a coin around 8 times in a row).

In general terms, experimental results are only considered to be real (as opposed to a coincidence) at the 5-sigma level (roughly equivalent to getting the same result when tossing a coin for more than 20 throws). I believe that the new analysis produced a value of 4.9-sigma for all the data, albeit that one of the two experiments being checked had a value of 5-sigma

....Sorry, blame a long-forgotten A-level Statistics course....and, if you're sad enough to want to know more about Standard Deviation, see here Wiki - StdDev...that should cure you :-)

"what does this higgs boson do?"

There is a pretty good in depth description here but in short it is part of the 'dark matter' of the universe that provides mass. Many of the reports also provide a brief description of its function.

Or if you wish to be flippant it is the antithesis of everything a dieter wishes for and is controlled by Darth Vader!!

As I understand it, it has something to do with what creates the weight of things. But on the other hand it could be a hiding place for our bankers ill gotten hidden wealth :-}

Now they (the scientists) have found the 'Higgs' will the demolition squads now 'move in' to dismantle the collider?

The Large Hadron Collider wasn't built just to search for the Higgs Boson. It has six detectors, each of which is designed for different types of research.

All those very fat women we see everywhere these days will be saying they suffer from higgs bosum syndrome then

Now they think they have found the "God" particle do you think they will now point in downwards and search for the "Devil" particle:-)

Condom I will get in before AitchBEE and say it could be 'the Devil in disguise'.
