High-energy physics aims to understand how Nature works at a fundamental level described by elementary particles. Our current theory, the Standard Model of particle physics, is remarkably successful: with its predictions confirmed by experiment to exceptional precision. However, a key piece, the 'Higgs boson', remained elusive until two years ago. Finding this new particle was just the start. Today we have gone beyond to clarify its nature, earning Peter Higgs and François Englert the Nobel Prize for Physics last year. We are also only just beginning to learn what the Higgs Boson can tell us of what new physics might be beyond the Standard Model.

Two years ago, the ATLAS and CMS experiments at the Large Hadron Collider, the worlds highest-energy particle accelerator, discovered a particle consistent with being a Higgs boson for the first time. Since then we have studied in detail this particle’s properties, including its mass, spin and its decays to other types of particles. The measurements have finally now established that the particle is indeed the Higgs boson that completes the Standard Model.

However, this discovery opens new doors to explore what we know cannot be the ultimate theory of Nature. Searches are ongoing for what lies beyond, including additional Higgs bosons, Supersymmetry, Dark Matter and Extra Dimensions. Planning is also underway for future accelerators and experiments that can take us to even higher energies and levels of precision. These include the 31km International Linear Collider and an even larger 100km circumference accelerator at CERN.

To do all this, high-energy physics needs large collaborations of thousands of scientists; huge, state-of-the-art detectors and electronics; and 'Big Data' computing. Those technologies are pushed to the limit, leading to applications beyond particle physics in the everyday world, from medicine to industry.
