Higgs boson scientists Peter Higgs from the UK and Belgium's Francois Englert have won the 2013 Nobel Prize for Physics.
They were among among several physicists in the 1960's who proposed a mechanism explaining why the Higgs boson particle, the universe's most basic building block, has mass.
The particle was discovered in 2012 Large Hadron Collider in Cern, Swizterland.
