This Project aims to supply the most precise to-date calculation of a critical parameter in cosmology, the effective number of neutrinos, in the context of the standard model of particle physics. Crucial to the correct interpretation of cosmological observations, this parameter enables the reconstruction of the universe's timeline from which to infer its properties. The expected outcome is a number of 4-digit significance that can be used in all future cosmological computations/analyses. Besides raising Australia's international profile in basic science research, this project expects to provide significant societal benefits via the training of HDRs in advanced mathematical modelling and computing, transferable skills across many sectors.

该项目旨在在粒子物理学标准模型的背景下，为宇宙学中的关键参数（中微子的有效数量）提供迄今为止最精确的计算。该参数对于正确解释宇宙学观测至关重要，它能够重建宇宙时间线，并从中推断其属性。预期结果是一些 4 位数的有意义的数字，可用于所有未来的宇宙学计算/分析。除了提高澳大利亚在基础科学研究方面的国际形象外，该项目还希望通过对 HDR 进行高级数学建模和计算以及跨多个领域的可转移技能的培训，带来重大的社会效益。
