Sound bites from interviews with Peter Higgs, Francois Englert, Carl Hagen and Gerald Guralnik. These were recorded at CERN on the announcement of the results from ATLAS and CMS on the Higgs boson searches last July.

At the smallest distance scales, the world can be understood in terms of apparently structureless objects, known as elementary particles. The behaviour of these particles is described by a set of theories referred to as the Standard Model of Particle Physics. The Standard Model successfully accounts for a wide variety of experimental observations, but links the origin of mass to a particle termed the ‘Higgs boson’, the existence of which has long remained unconfirmed.

How it works

In July 2012, the ATLAS and CMS experiments at the Large Hadron Collider (LHC), the world's highest-energy particle accelerator, announced the discovery of a new particle consistent with the Higgs boson. Studies in progress will measure the properties of this particle, to determine whether it's the Higgs boson of the Standard Model, or something more exotic. Either way, results will provide new insight into how the Universe is made.

The search for the Higgs boson is science on an epic scale. It is a quest that has spanned half a century, creating some of the most ambitious scientific experiments ever seen. Experiments prior to the first LHC collisions, in November 2009, found no clear evidence for the existence of the Higgs boson, but placed constraints on its mass.

The ATLAS and CMS experiments have discovered a new particle that, from initial measurements, has mass, production rate and decay probabilities consistent with the Higgs boson. The extraction of the small signal for the new particle, from a background of trillions of proton-proton collisions, has relied on high-performance detectors for particle identification and measurement, ultrafast electronics for filtering during data collection, sophisticated data-processing algorithms and massive calculational power, provided by a worldwide computing grid.
