Discovery of Higgs Boson

About 2 weeks ago, two teams of physicists at the CERN laboratory near Geneva reporting from the Large Hadron Collider (LHC) the discovery of a new particle consistent with the Higgs boson, one of the most important missing pieces of the jigsaw puzzle in nature.

The key to finding this particle is Large Hadron Collider (LHC) at CERN in Geneva, Switzerland, the most powerful particle accelerator and one of the most complicated scientific instruments ever built with a monstrous doughnut-shaped machine 27 miles in circumference, so big it straddles the French-Swiss border.

Scientists at the Large Hadron Collider near Geneva smashed together beams of protons – the ‘hearts of atoms’ – at close to the speed of light, recreating conditions that existed a fraction of a second after the Big Bang.

If the theory of Higgs boson’s existence was right, a few Higgs bosons should have been created in every trillion collisions. Although they would rapidly decay, they should have left a recognisable footprint.

On July 4, 2012 the scientists at CERN have claimed the discovery of a “Higgs-like” particle (but with 99.9999% confidence, they can claim to have found the Higgs boson itself.)

What is the Higgs boson?

Higgs boson is a proposed elementary particle in the Standard Model of particle physics. The Higgs boson’s role is to give the particles that make up atoms their mass. Without this mass, they would zip around the cosmos, unable to bind together to form the atoms that make stars and planets and people. Without Higgs boson will mean there is nothing in this universe.
