This project will perform supercomputer simulations to resolve the distribution of forces acting on quarks inside the proton. New knowledge will be generated in the area of fundamental strong-interaction physics by developing innovative approaches to image novel features that have not been possible in the past. The outcomes will therefore open new research possibilities by expanding the capacity of the international community to study strong interaction physics—including direct relevance to experimental research at the recently-upgraded Jefferson Lab in the US. In analogy to Rutherford's atomic model, the results will have benefit to future generations of humanity with a deeper understanding of the structure of matter.Read moreRead less
Nuclear vibrations under scrutiny in near-spherical and deformed nuclei. This Project aims to elucidate the nature of nuclear vibrations. Evidence is mounting that nuclear excitations long identified as vibrations cannot truly be so. This shakes the foundations of nuclear theory.

This Project aims to elucidate the nature of nuclear vibrations. Evidence is mounting that nuclear excitations long identified as vibrations cannot truly be so. This shakes the foundations of nuclear theory. Coulomb excitation and transfer reaction experiments are to be developed to probe the structure of these quantum states. Expected outcomes include clarification of their true nature and a deeper understanding of why nuclei differ from other many-body quantum systems that do vibrate. Anticipated benefits include enduring methodologies to facilitate international research engagement, and rigorous hands-on training in nuclear methods, to help meet Australia’s need for nuclear-qualified personnel in health, mining, industry and security.Read moreRead less

Connecting Quantum Chromodynamics to experiment via non-perturbative effective field theory. This project aims to disclose the composition of proton excited states by advancing the theoretical formalism governing the underlying dynamics. At present, the structure of even the first excited state of the proton, the Roper, remains unknown for more than 50 years following its discovery.

This project aims to disclose the composition of proton excited states by advancing the theoretical formalism governing the underlying dynamics. At present, the structure of even the first excited state of the proton, the Roper, remains unknown for more than 50 years following its discovery. While the fundamental theory of Quantum Chromodynamics (QCD) describes the interactions between the quarks and gluons composing these states, the phenomena that emerge from QCD are complex and require dedicated analyses to understand them. The intended outcome is the creation of the effective field theory required to decipher QCD calculations.Read moreRead less
