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."

"The discovery reported in these papers is a momentous step forward in fundamental knowledge," says ATLAS spokesperson Fabiola Gianotti. "It is the culmination of more than 20 years of effort of the worldwide high-energy physics community to build and operate instruments of unprecedented technology, complexity and performance: the LHC accelerator and related experiments."

Note:

CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the Universe is made of and how it works. At CERN, the world’s largest and most complex scientific instruments are used to study the basic constituents of matter — the fundamental particles. By studying what happens when these particles collide, physicists learn about the laws of Nature.

The instruments used at CERN are particle accelerators and detectors. Accelerators boost beams of particles to high energies before they are made to collide with each other or with stationary targets. Detectors observe and record the results of these collisions.

Founded in 1954, the CERN Laboratory sits astride the Franco–Swiss border near Geneva. It was one of Europe’s first joint ventures and now has 20 Member States.
