Elucidating the role of quantum electrodynamics in hadron properties

该项目将探索自然界使中子比质子重的基本机制;控制哪些原子核是稳定的;并确定宇宙的当前状态。利用国际合作提供的大量超级计算资源，该项目将进行第一次从头计算模拟，结合了管理基本夸克、胶子、电子和光子的量子场论，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贡献强子性质，并在这样做，解决了广泛的重要方面的强子结构和相互作用。

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.
