Scientists had discovered a new particle whose characteristics match those of the Higgs boson, the most sought-after particle in physics, which could help unlock some of the universe's deepest secrets.
They had crept closer to proving the existence of the Higgs boson but had been unable to reach a definitive conclusion. The U.S.-based scientists outlined their final analysis based on more than 10 years of research and 500 trillion particle collisions using the U.S. Department of Energy's Fermilab Tevatron collider near Batavia, Illinois, whose budgetary woes shut it down last year.
They passed the baton onto their counterparts using the LHC, which is much more powerful than the Tevatron. Located 328 feet underneath the border of France and Switzerland, the LHC cost $10 billion and has been sending particles smashing together in 17-mile tunnel for the past 18 months. High speed proton collisions generate a range of even smaller particles that scientists have been sifting through in search of a signal in the data suggesting the existence of the Higgs boson.The elusive particle is part of a theory first proposed by physicist Peter Higgs and others in the 1960s to explain how particles obtain mass.The theory proposes that a so-called Higgs energy field exists everywhere in the universe. As particles zoom around in this field, they interact with and attract Higgs bosons, which cluster around the particles in varying numbers.
Imagine the universe like a party. Relatively unknown guests at the party can pass quickly through the room unnoticed; more popular guests will attract groups of people (the Higgs bosons) who will then slow their movement through the room. The speed of particles moving through the Higgs field works much in the same way. Certain particles will attract larger clusters of Higgs bosons -- and the more Higgs bosons a particle attracts, the greater its mass will be.
Why is finding the Higgs boson so important?
While finding the Higgs boson won't tell us everything we need to know about how the universe works, it will fill in a huge hole in the Standard Model that has existed for more than 50 years, according to experts. The Higgs boson is the last missing piece of our current understanding of the most fundamental nature of the universe. Only now with the LHC [Large Hadron Collider] are we able to really tick that box off and say 'This is how the universe works, or at least we think it does'. It's not the be all and end all -- but in terms of what can we say practically about the world and how the world is, it actually tells us a lot.
Gordon Kane, director of the Michigan Center for Theoretical Physics, said that the finding evidence of the Higgs boson would be a "very wonderful success of science and of people for four centuries."
Physicist Martin Archer said "Higgs boson is the last missing piece of our current understanding of the most fundamental nature of the universe".
