Welcome to High-Energy Physics at the University of Adelaide, and the Adelaide node of the ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP).
Firstly, what is "high-energy physics"? Broadly speaking, high-energy physics (also referred to as "particle physics") is the examination of the very smallest constituents of matter- the indivisible particles from which all matter is made, as well as the study of their interactions and the forces which govern their behaviour.
Why "high-energy"? In order to break apart the ever-smaller building blocks of matter, it is necessary to cause these constituents to collide with higher and higher energies, at speeds very close to the speed of light.
And further, even though high-energy physics works with structures at the very smallest scales, its scope of investigation includes the very largest of scales- the formation and evolution of the universe itself...
The High-Energy Physics (HEP) group at Adelaide undertakes research into these elementary constituents of matter and their interactions. The group has both experimental and theoretical research programs, with a particular emphasis on studying physics at the Large Hadron Collider (LHC) and theories of Beyond the Standard Model physics.
This also involves close collaboration with the Centre for the Subatomic Structure of Matter (CSSM) and the High-Energy Astrophysics group. As a node of CoEPP, we also work both with the other national nodes of CoEPP and with international partners, including involvement with the ATLAS experiment, to explore the energy and precision frontiers of particle physics.
