CERN: Evidence of Higgs Boson Particle Discovered

One event with two muons (tracks in red) and two electrons (tracks in green) found by CMS.

The two teams at the CERN Large Hadron Collider, CMS and ATLAS, have reported their results to-date in the search for the Standard Model Higgs Boson. The particle discovered is most  likely the Higgs Boson but additional research is necessary. A 5 sigma confidence is considered a discovery and adequate confidence (odds are less than 1 in 3.5 million that it was produced by chance).

Peter Higgs, 83, who first proposed the idea of the boson in 1964 was present and cried at the end of the presentation. "For me it's a really incredible thing that it's happened in my lifetime".

Joe Incandela of the CMS (Compact Muon Solenoid) team confirmed that a particle has been discovered that is consistent with the Higgs boson theory. The new boson has a mass 125.3GeV (+-0.6) with a 4.9 sigma confidence.

Fabiola Gianotti of the ATLAS team confirmed a Higgs-like boson particle has been discovered at a mass of 126.5GeV with a 5.0 sigma confidence.

Cern Scientists Announce Higgs Boson Discovery Scientists at the Cern research centre in Switzerland reveal they have found a new subatomic particle that could be the Higgs boson. The announcement was greeted by rousing cheers and a few tears from the audience. The finding marks a breakthrough in understanding of the fundamental laws that govern the universe.



The Discovery of the Higgs Boson? Garrett Lisi Explains Following the CERN announcement, Theoretical physicist Garrett Lisi explains the discovery of the Higgs Boson particle by CERN scientists. 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.



The Higgs Boson: Fireworks or Flameout? Theoretical Physicist Dr. Michio Kaku says that even with strong evidence of the Higgs Boson, it is not time to pop the champagne. Next up: use the Large Hardon Collider to find dark energy.

What Is a Higgs Boson? Fermilab scientist Don Lincoln describes the nature of the Higgs boson. Several large experimental groups are hot on the trail of this elusive subatomic particle which is thought to explain the origins of particle mass.
