CERN says Higgs Boson does exist

Finally, CERN scientists announced that they proved existence of the most wanted particle, Higgs Boson.

Both parallel going experiments ATLAS and CMS confirmed existence of the slippery little article Higgs boson with a result of 5 sigma certainty. To explain what this means, on a scale of certainty 1 sigma means the results could be a random fluctuations in the data, 3 sigma goes as an observation and a 5 sigma counts as a discovery.

The strong indications of ATLAS and CMS experiments show evidence for the particle's presence with the mass around 126 GeV (giga electron volts). Electron Volt or eV is equal to the work requires to move one electron through a potential difference of 1 Volt. The good people of CERN say the results are still preliminary and they need to complete the analysis for the final confirmation of Higgs boson existence.

In the video bellow we can see real CMS (Compact Muon Solenoid - one of the too large general-purpose particle physics detectors) events in which two muons (light purple lines) and two electrons (dark orange lines and yellow towers) are observed in proton-proton collisions at a centre-of-mass energy of 8 TeV. The event shows characteristics expected from the decay of a Higgs boson but is also consistent with background Standard Model physics processes.
