This project aims to use data from a Large Hadron Collider experiment, ATLAS, to investigate basic questions in physics. The project expects to use innovative analysis techniques to test the current model of fundamental particles and interactions. While the model, now completed by the Higgs boson discovery, agrees well with observations it cannot be Nature's ultimate description. 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

Summary
Bridging the accuracy gap: High-precision parton showers for colliders. This project aims at improving the accuracy of parton showers, which are an essential ingredient used in the simulation of high-energy particle collisions. Parton showers generate the large set of particles produced in a collision, in an approximation of the radiation pattern of Quantum Chromodynamics. The low precision of this approximation translates into large uncertainties in critical measurements performed at particle c ....Bridging the accuracy gap: High-precision parton showers for colliders. This project aims at improving the accuracy of parton showers, which are an essential ingredient used in the simulation of high-energy particle collisions. Parton showers generate the large set of particles produced in a collision, in an approximation of the radiation pattern of Quantum Chromodynamics. The low precision of this approximation translates into large uncertainties in critical measurements performed at particle colliders. This project will study novel ways of enhancing the precision of parton showers, and determine accurate estimates of associated uncertainties across all processes under investigation at the Large Hadron Collider. It will be of exceptional importance for the latter's high-precision, high-luminosity program.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
