This project will explore the fundamental mechanisms of nature making the neutron heavier than the proton; governing which nuclei are stable; and determining the current state of the Universe. Drawing on substantial supercomputing resources made available through international collaboration, this project will perform the first ab-initio simulation combining the quantum field theories governing elementary quarks, gluons, electrons and photons; namely quantum chromodynamics and quantum electrodynamics. This project will develop novel theoretical and numerical techniques to confront the otherwise elusive electromagnetic contributions to hadronic properties and in doing so, address a wide range of important aspects of hadron structure and interactions.

该项目将探索自然界使中子比质子重的基本机制；决定哪些原子核是稳定的；并决定宇宙的当前状态。利用国际合作提供的大量超级计算资源，该项目将首次结合基本夸克、胶子、电子和光子的量子场理论进行从头算模拟；即量子色动力学和量子电动力学。该项目将开发新的理论和数值技术，以面对其他难以捉摸的电磁对强子性质的贡献，并在此过程中，解决强子结构和相互作用的广泛重要方面。
