Landmark Higgs Boson Discovery Published In Physics Journal

Higgs Boson Discovery
The landmark ATLAS and CMS experiments at CERN have 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.
Physics Letters B, Elsevier’s journal in high energy physics, has announced that the observations of the long-sought Higgs particle, hailed as one of the greatest scientific discoveries of all time, have been published.

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 now.

Read the Papers:

"Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHC" 
"Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC"

In July 2012, The European Organization for Nuclear Research (CERN) in Geneva announced they had captured a new particle that may be the elusive Higgs boson in two gigantic experiments, ATLAS and CMS, both of which independently confirmed the particle’s existence. A world-wide collaboration of more than 5,000 researchers contributed to the discovery.

"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,” explains physicist Joe Incandela, spokesperson of the CMS experiment. “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,” added ATLAS experiment 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.”

The existence of the Higgs particle was first predicted in 1964 by three groups of leading physicists independently — Fran├žois Englert and Robert Brout in August, Peter Higgs in October, and Gerald Guralnik, C. R. Hagen, and Tom Kibble (GHK) in November. Its discovery completes the Standard Model of particle physics and, most importantly, validates the theories developed over the last 50 years explaining how elementary particles can have mass.

The Story of the Chessboard


The classic parable of how the inventor of the game of chess used his knowledge of exponential growth to trick an emperor is commonly used to explain the staggering and accelerating growth of technology. The 33rd square on the chessboards represents the first step into the second half of the chessboard, where exponential growth takes off.

33rd Square explores technological progress in AI, robotics, genomics, neuroscience, nanotechnology, art, design and the future as humanity encroaches on The Singularity.
