ATLAS and CMS publish observations of a new particle in the search for the Higgs boson
10 September 2012
The ATLAS and CMS experiments at CERN today published observations of a new particle in the search for the Higgs boson in the journal Physics Letters B.
The papers: “Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC” and “Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHC” are freely available online on ScienceDirect.
“These papers present the first observations of a new particle discovered by two big experiments at the Large Hadron Collider (LHC) in the search for the Standard Model Higgs boson which has spanned many decades and has involved many experiments,” says CMS spokesperson Joe Incandela. “They are the most important papers to come from the LHC so far and the findings are key to the field of particle physics. We are very pleased to see them published in Physics Letters B, accessible to all who may want to read them.”

Higgs boson results from LHC ‘get even stronger’
August 3, 2012
The particle has been the subject of a decades-long hunt as the last missing piece of physics’ Standard Model, explaining why matter has mass.
Now one Higgs-hunting team at the Large Hadron Collider report a “5.9 sigma” levels of certainty it exists.
That equates to a one-in-550 million chance if the Higgs did not exist, the team would see these same results.
The formal threshold for claiming the discovery of a particle is a 5-sigma level – equivalent to a one-in-3.5 million chance.
That is the level that was claimed by the team behind Atlas, one of the LHC’s Higgs-hunting experiments, during the 4 July announcement. The other, known as CMS, claimed results between 4.9 and 5 sigma.

Higgs boson: scientists 99.999% sure ‘God Particle’ has been found
July 4, 2012
Scientists believe they have captured the elusive “God particle” that gives matter mass and holds the physical fabric of the universe together.
The historic announcement came in a progress report from the Large Hadron Collider particle accelerator.
Professor John Womersley, chief executive of the Science and technology Facilities Council, told reporters at a briefing in London: “They have discovered a particle consistent with the Higgs boson.
“Discovery is the important word. That is confirmed. It’s a momentous day for science.”
Scientists say it is a 5 sigma result which means they are 99.999% sure they have found a new particle.
Finding the Higgs plugs a gaping hole in the Standard Model, the theory that describes all the particles, forces and interactions that make up the universe.
Watch Live: Higgs Boson Announcement
July 4, 2012

Officials at CERN will finally be revealing their latest results in the search for the Higgs boson during a talk starting at midnight PT (3 a.m. ET) on July 4.
Physicists have been eagerly waiting for this announcement, with hopes running high that the new data will pin down Higgs boson with enough precision to consider it discovered. Previously, LHC results have strongly signaled the existence of a Higgs with a mass of 125 gigaelectronvolts (GeV), or roughly 125 times more massive than the proton. More recently, rumors have been flying that suggest this talk will be the definitive announcement of the long-sought boson’s discovery.
