This project aims to deliver a breakthrough technique in theoretical-computational particle physics, with significant potential for high-precision applications. The project targets some of the most advanced and resource-intensive calculations in particle physics, which are widely used but currently limited by extremely high computational resource requirements. This project expects to develop a novel approach that will vastly reduce the computational complexity while at the same time improving their accuracy relative to the current global state of the art. Expected outcomes include the new methodology itself as well as a full-fledged and open-access simulation code based on it, which should be highly efficient.Read moreRead less

This project aims to uncover the new theory of particle physics that can simultaneously explain the Higgs mechanism, the presence of dark matter and the current abundance of matter over antimatter in our universe. This is not possible with current theories. This project aims to find viable theories using a wide range of data from particle astrophysics and collider experiments. With the resulting knowledge, this project aims to design, optimise and implement better searches for new physics at the Large Hadron Collider (LHC). The new LHC results will be used to either determine the correct explanation for any new discoveries or alternatively to provide definitive limits on new theories. The results will be used to make high impact statements on the design of future facilities.Read moreRead less

New technology developed by Australia, Sweden and the United States will be applied to major questions about the application of relativistic quantum mechanics to atomic structure and dynamics and spectroscopy, especially including critical issues in quantum electro-dynamics for atomic physics and applications. Discrepancies in quantum electro-dynamics have dominated international debate for decades, with claimed explanations annually failing to reveal the cause. Also a pattern of discrepancies has been seen at X-ray energies in first row metal atoms, with a similar sign and magnitude. A combined experimental an theoretical investigation will aim to reveal new light on these anomalies and serve to develop our understanding of the universe.Read moreRead less

It is one of the most precisely measured and validated theories which science has produced, and there has as yet been no measurement of fundamental particle interactions which is in conflict with its predictions. This project involving a large international team and highly sophisticated technology will search for evidence of physics beyond the Standard Model by looking for conversion of muons to electrons a reaction which the model prohibits. Observation of this process would be evidence of new particles and interactions, and would revolutionise our understanding of nature.Read moreRead less
