Violation of the fundamental symmetries is predicted by unification theories of elementary particles. The aim of this project is to propose new enhanced effects of parity, time reversal and Lorentz invariance violations and perform their calculations needed to test unification theories in atomic and nuclear phenomena. By-products of this project include development of high precision computer codes for atomic calculations and theory of processes involving atoms and nuclei in chaotic excited states. These codes and theory are expected to have numerous applications (e.g. search for Dark Matter and atomic spectra of superheavy elements, atomic clocks and electron and photon processes).

New Physics and the quark/lepton family replication puzzle. This project aims to investigate how new physics impacts on the puzzling threefold replication of the elementary particles known as quarks and leptons; these particles provide the foundations for the structure of atoms.

This project aims to investigate how new physics impacts on the puzzling threefold replication of the elementary particles known as quarks and leptons; these particles provide the foundations for the structure of atoms. This theory project seeks to do so in the context of a concentrated worldwide experimental program whose objective is to produce hugely more information about the mysterious replication. Expected outcomes include the construction of new theories that deepen our understanding of elementary particles and their interactions. This should provide significant benefits to intellectual culture and the training of early-career researchers as flexible problem solvers able to innovate in any context in industry or government service.Read moreRead less

Searching for New CP Violating Phenomena at the Intensity Frontier. This project aims to search for new sources of matter-antimatter asymmetry in B-meson decays at the intensity frontier, using data from the Belle and Belle II experiments at Japan's KEK collider facility. It aims to do this by optimally utilising an innovative analysis approach based on advanced machine learning techniques and fitting methods.

This project aims to search for new sources of matter-antimatter asymmetry in B-meson decays at the intensity frontier, using data from the Belle and Belle II experiments at Japan's KEK collider facility. It aims to do this by optimally utilising an innovative analysis approach based on advanced machine learning techniques and fitting methods. It could resolve long-standing puzzles such as the origin of the matter-antimatter asymmetry in the universe. Expected outcomes include broader knowledge in the field of particle physics and enhancement of international collaboration. This should provide significant benefits for Australia's international scientific reputation, leading to increased export opportunities for Australian education.Read moreRead less

The origin of mass and mass hierarchies remains arguably the major unresolved problem in particle physics. This project aims to introduce and explore a conceptually new paradigm to address this problem by promoting scaling invariance as a fundamental symmetry of Nature. Namely, we will establish an entirely new realisation of quantum scale invariance within a theoretically consistent picture of the relativistic theory of gravitation and explore its phenomenological, cosmological and astrophysical implications. The anticipated results will likely lead to transformational advancements in particle physics and cosmology and serve as an important theoretical guide for new physics searches in ongoing and future experimental programs worldwide.

Explaining the dark matter small-scale crisis with spectral distortions. This project aims to explain the nature of dark matter and provide a solution to the so-called small-scale crisis. The "cold dark matter" model provides an excellent fit to observations of the universe on the largest scales. Yet, it appears to be in conflict with current understanding of how small structures such as dwarf galaxies form. This project expects to determine the distortions to the blackbody spectrum of the cosmi ....Explaining the dark matter small-scale crisis with spectral distortions. This project aims to explain the nature of dark matter and provide a solution to the so-called small-scale crisis. The "cold dark matter" model provides an excellent fit to observations of the universe on the largest scales. Yet, it appears to be in conflict with current understanding of how small structures such as dwarf galaxies form. This project expects to determine the distortions to the blackbody spectrum of the cosmic microwave background (CMB) photons due to different solutions to this small-scale crisis. The expected outcome is to open an observational pathway to test these solutions with the future CMB observations. This project will provide significant contribution to both particle physics and astrophysics/astronomy, and will advance Australia’s knowledge base in fundamental science beyond the immediate goal of clarifying small-scale problems of cold dark matter.Read moreRead less

This project aims to propose and assist in the development of novel approaches, based on atomic, molecular and optical technologies, to detect dark matter in the laboratory, and thereby establish the identity and microscopic properties of dark matter. The origin and nature of dark matter remains one of the most important outstanding problems in contemporary science. The intended outcome of this project is that the use of our novel methods will enable us to search for forms of dark matter that have remained largely unprobed to date. This in turn is expected to open up new opportunities in the global hunt for dark matter that should improve our chances of finally discovering the nature and properties of dark matter.Read moreRead less

This project aims to connect the particle and astrophysics of dark matter so as to accelerate us towards its first detection in the lab. The expected outcomes are 1) new experimental concepts to test the widening landscape of viable theories and 2) robust predictions for signals in those experiments backed up by the latest surveys of our Milky Way. These outcomes should benefit experiments across the world on the quest to fill a major gap in our understanding of the Universe. The grand scope of this research aims to place Australia in the vanguard of one of the most active pursuits of new physics in the modern era.Read moreRead less

This project aims to develop an underground integrated laboratory at Stawell Gold Mine in Victoria to host the Southern Hemisphere's first-ever direct-detection dark matter experiment. Following the Higgs boson discovery, the direct detection of dark matter is seen as the next major challenge for particle physics. This project sees Australian physicists team up with local and international partners in research and industry to join the search for dark matter. This Australian experiment aims to help to confirm or deny current results from Northern Hemisphere experiments. As the mine nears the end of its working life as a gold mine, this project is expected to benefit the local economy and provide opportunities for education and outreach.Read moreRead less
