This project will perform supercomputer simulations to confront one of the outstanding puzzles of nuclear and particle physics, the neutron lifetime. New knowledge will be generated through the development of novel theoretical and numerical techniques to increase the precision of the leading theoretical inputs required to predict the neutron lifetime. The outcomes will provide crucial theoretical guidance into understanding the neutron; helping to guide the next-generation neutron experiments, from particle physics to applications in advanced materials science. The results will have immediate benefit by resolving the neutron lifetime puzzle, while enabling Australian scientists to take a leadership role in this area of fundamental science.Read moreRead less
Excitation spectra of quantum chromodynamics. Just as quantum electrodynamics describes the quantum mechanical excitation spectra of atomic systems, quantum chromodynamics (QCD) describes the excitation spectra of quark and gluon systems, such as the proton. This project will resolve the interactions underpinning the excitations of QCD, as being investigated at international facilities.
Interplay of the forces of nature: electroweak and strong interactions. The Large Hadron Collider in Switzerland will search for new physics by smashing protons together at the highest energies ever created in the laboratory. This project will focus on complementary searches for new physics by investigating novel phenomena associated with the mutual interactions of the strong and weak forces of nature.
Elucidating the role of quantum electrodynamics in hadron properties. This project will explore the fundamental mechanisms of nature making the neutron heavier than the proton; governing which nuclei are stable; and determining the current state of the Universe. Drawing on substantial supercomputing resources made available through international collaboration, this project will perform the first ab-initio simulation combining the quantum field theories governing elementary quarks, gluons, electr ....Elucidating the role of quantum electrodynamics in hadron properties. This project will explore the fundamental mechanisms of nature making the neutron heavier than the proton; governing which nuclei are stable; and determining the current state of the Universe. Drawing on substantial supercomputing resources made available through international collaboration, this project will perform the first ab-initio simulation combining the quantum field theories governing elementary quarks, gluons, electrons and photons; namely quantum chromodynamics and quantum electrodynamics. This project will develop novel theoretical and numerical techniques to confront the otherwise elusive electromagnetic contributions to hadronic properties and in doing so, address a wide range of important aspects of hadron structure and interactions.Read moreRead less
Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited sta ....Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited states using the first principles approach of lattice gauge theory. By elucidating aspects of hadron structure in terms of the most fundamental non-perturbative quark and gluon fields, the project will create new knowledge impacting on renowned experimental programs at international facilities.Read moreRead less
