PARTICLE 'CONSISTENT' WITH HIGGS BOSON DISCOVERED
The discovery of a particle consistent with the Higgs boson has been announced by physicists from the Large Hadron Collider's CMS and ATLAS detectors.
The discovery was detailed at a major conference to update the world on the continuing efforts by CERN scientists to find the last remaining piece of the Standard Model that underpins the foundations of our Universe. The Higgs boson mediates the "Higgs field" that ultimately endows all matter with mass -- finding the Higgs is therefore imperative for physicists to understand what gives the Universe substance.
When reports first surfaced that Peter Higgs -- one of the six physicists who, in the 1960s, developed the theory behind Higgs boson -- had been invited to CERN for this morning's announcement, the event became hard to ignore: something historic was about to happen...
This "new boson" revealed itself in the CMS data as a "bump" at 125 GeV/c2, a value that places it at over 130 times more massive than a proton.
After combining all the results gathered over many different channels in the CMS, the level of certainty -- 4.9-sigma -- came tantalizingly close to the "Gold Standard" (5-sigma) for subatomic particle discovery. This means there is a one-in-2 million chance of the result being a random fluctuation, or noise. For all intents and purposes, this is a discovery of a particle that acts very much like a Higgs boson...
However, more work needs to be done to figure out if this is indeed a Higgs boson or some unexpected renegade particle that just acts like the Higgs (although the latter is highly unlikely). Also, if it is a Higgs boson, is it a part of a larger Higgs family of particles?...
"I think we have it," said CERN Director-General Rolf Heuer. "We have discovered a particle that is consistent with a Higgs boson."
Physicists Find Elusive Particle Seen as Key to the Universe
Published: July 4, 2012
ASPEN, Colo. — Signaling a likely end to one of the longest, most expensive searches in the history of science, physicists said Wednesday that they had discovered a new subatomic particle that looks for all the world like the Higgs boson, a key to understanding why there is diversity and life in the universe...
I think we have it,” said Rolf-Dieter Heuer, the director general of CERN, the multinational research center headquartered in Geneva. The agency is home to the Large Hadron Collider, the immense particle accelerator that produced the new data by colliding protons. The findings were announced by two separate teams. Dr. Heuer called the discovery “a historic milestone.”
'God particle' find sets scene for one hell of a row

It was announced less than 24 hours ago, but rows over who deserves credit have already broken out.
It’s good news for physicists, but a big headache for the Nobel committee.
The discovery - or near discovery - of the Higgs boson, will see someone win a Nobel prize, but deciding who deserves credit for the work is a minefield. Traditionally, the science Nobel prizes are given to a maximum of three people, whose contributions are judged to be the most important.
