Particle physics

Particle physics is a branch of physics that investigates the fundamental constituents of our Universe. The nature of particles, matter, radiation and forces of nature are all studied by particle physicists. Researchers at CERN, the European Organization for Nuclear Research, are probing subatomic particles such as quarks, leptons and bosons. In 2012 the ATLAS and CMS experiments at CERN announced the discovery of the Higgs boson, a particle predicted by the Standard Model of particle physics.

Why the promise of nuclear fusion is no longer a pipe dream

Fusion – combining atomic nuclei to release energy – is a clean and safe way to power our homes and industry. This ‘holy grail’ of energy has eluded physicists for decades, but there are signs that a bright future could be on the horizon.
