High-Energy Physics

High momentum mono-jet event

The High-Energy Physics Group (HEP) at the University of Adelaide are experts in both experimental and theoretical research.

Our research focuses on studying physics at the Large Hadron Collider (LHC) and theories of Beyond the Standard Model physics.

HEP is also home to the Adelaide nodes of the ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP), and of the ARC Centre of Excellence for Dark Matter Particle Physics.

The search for new physics

The fundamental (or elementary) particles plus the four known forces summarise our current understanding of the Universe. These are:

  • gravity;
  • electromagnetism;
  • the weak interaction; and
  • the strong interaction.

The last three forces have been combined into the Standard Model (SM) of particle physics.

The Standard Model successfully predicted the W and Z bosons, the top quark, the tau neutrino and, most recently, the Higgs boson (discovered in 2013). The Standard Model does not include dark matter, dark energy or gravity, so it is incomplete.

The search for additional evidence of new physics Beyond the Standard Model (BSM), and the development of new theories that extend the SM, such as supersymmetry (SUSY), are the core activities in modern high-energy physics.
