Expected outcomes include a sensitive investigation of whether the highest energy particle collisions ever recorded hold evidence for a deeper theory. Significant benefits will be an advancement of fundamental knowledge, cutting-edge training of young scientists, strengthening of Australian participation in international science, and public engagement with science.Read moreRead less

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.

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

The goal of the project is to develop a comprehensive space radiation monitoring system (SRAMS) that can evaluate: i) the radiation related hazards for astronauts, ii) the radiation damage in electronics during space missions and iii) the ground radiation facility environment used in radiation hardness assurance tests. SRAMS will also address important issue in space by minimizing manned or satellite space mission aborts due to space radiation adverse effects on astronaut’s health and electronics failure, and translates into an enormous economic value proposition. SRAMS will be paramount for leveraging the quantifiable standards of the space-radiation qualification facilities that are important for boosting the Australian Space industry. Read moreRead less
