Project NT aims at providing first principles calculations of nuclear structure and reactions with quantified uncertainties using state-of-the-art few- and many-body methods. This is key to interpret existing data, provide guidance for future experiments and help searches of new physics in atomic and particle physics experiments at the interface with nuclear physics. On the few-body front, the major goal is to provide improved calculations of nuclear structure corrections to the Lamb shift in muonic atoms and to obtain first calculations of nuclear structure corrections to the hyperfine splitting in 𝜇D and 𝜇3He+. On the many-body front, the aim is to perform improved calculations of photonuclear reactions and novel computations of lepton-nucleus collisions using coupled-cluster theory. Theoretical studies of neutron-skin thickness and, in general, of electromagnetic processes in few- and many-body nuclear systems will complement at various levels the present CRC 1044 experimental efforts with a much needed nuclear theory component.

NT计划的目的是利用最先进的少体和多体方法，提供核结构和反应的第一性原理计算和量化不确定性。这是解释现有数据的关键，为未来的实验提供指导，并有助于在原子和粒子物理实验中寻找与核物理学相结合的新物理。在少体方面，主要目标是提供对μ子原子Lamb位移的核结构修正的改进计算，并获得𝜇D和𝜇3He+中超精细分裂的核结构修正的首次计算。在多体前沿，目标是使用耦合簇理论进行改进的光子核反应计算和轻子-核碰撞的新计算。中子蒙皮厚度的理论研究，以及一般来说，在少体和多体核系统中的电磁过程的理论研究，将在各个层面上补充目前CRC 1044的实验努力，并提供急需的核理论成分。
