Mystery Signal At Fermilabs

Article entitled: Mystery signal at Fermilab hints at 'technicolour' force

The physics world is buzzing with news of an unexpected sighting at Fermilab's Tevatron collider in Illinois – a glimpse of an unidentified particle that, should it prove to be real, will radically alter physicists' prevailing ideas about how nature works and how particles get their mass.
The candidate particle may not belong to the standard model of particle physics, physicists' best theory for how particles and forces interact. Instead, some say it might be the first hint of a new force of nature, called technicolour, which would resolve some problems with the standard model but would leave others unanswered.
The observation was made by Fermilab's CDF experiment, which smashes together protons and antiprotons 2 million times every second. The data, collected over a span of eight years, looks at collisions that produce a W boson, the carrier of the weak nuclear force, and a pair of jets of subatomic particles called quarks.
Physicists predicted that the number of these events – producing a W boson and a pair of jets – would fall off as the mass of the jet pair increased. But the CDF data showed something strange (see graph): a bump in the number of events when the mass of the jet pair was about 145 GeV.
Just a fluke?

That suggests that the additional jet pairs were produced by a new particle weighing about 145 GeV. "We expected to see a smooth shape that decreases for increasing values of the mass," says CDF team member Pierluigi Catastini of Harvard University in Cambridge, Massachusetts. "Instead we observe an excess of events concentrated in one region, and it seems to be a bump – the typical signature of a particle."

Currently speculative, but we'll see. A new discovery is always exciting, even if it possibly breaks the proverbial mould

Nice one Slade_X!

The Alpha Magnetic Spectromator to launch on the next shuttle mission is designed to work hand in hand with the collider.............. add to that the research the Kepler mission is carrying out we might just wake up soon to astonishing and verified News............... just may'be there will be life after shuttle!:)

So does this mean Fermilab bet CERN?

this isn't Higgs (if it exists) so in that sense noone beat anyone,
fermilab have done massive amounts of work in that area though which is a pity it is to shut down soon as they deserve alot of credit for a smaller collider. it is really early days on this 'discovery' too.

ah come on now lads, who ordered this one.
