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: 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.

Tantalizing Signs of Higgs Boson Found By U.S. Tevatron Collider


By Rebecca Boyle Posted 07.02.2012

If the Tevatron was a metal detector sweeping across a proverbial beach, the beeps of discovery would have been coming in very close succession at the end of its life. It was, we have learned, extremely close to finding the treasured Higgs boson … and then, last September, it shut down. Only another, more powerful detector, owned by someone else, will finally be able to grab it.
