Theoretical Physics

Our theoretical physics researchers are internationally renowned for their research exploring the fundamental quantum field theories of the Standard Model of the Universe.

We are home to the Centre for the Subatomic Structure of Matter (CSSM), in which significant advances have been made in unveiling the nature of Quantum Chromodynamics (QCD) - the theory describing the interactions between quarks and gluons as they compose particles such as the proton. 

Our research supports nuclear and particle physics facilities around the world, revealing the most fundamental aspects of nature and exploring the extreme conditions of the early universe.
