Professor Peter Higgs, the retired British physicist from Edinburgh University after whom the particle was named, was present at a packed seminar at the Geneva headquarters of Cern, the European Organisation for Nuclear Research.
The professor dreamed up the concept of the Higgs mechanism to explain mass while walking in the Cairngorms in 1964.
Scientists think the Higgs boson has been found, but what is it and for you and me, what does it all mean?
Scientists believe they have found the elusive "God particle" that gives matter mass and holds the physical fabric of the universe together
Researchers from CERN are due to announce the discovery of Higgs boson, an elusive particle which they think creates mass in the universe.
