核物理旨在阐明由强相互作用粒子组成的量子多体系统的性质和动力学，即，强子夸克和胶子虽然这个领域的基本理论是量子色动力学（QCD），但目前还不可能将QCD直接应用于核物理中的实际问题，这主要是在QCD的非微扰区。从纯粹的现实核子-核子相互作用出发解决各种核物理问题，目前也是不可能的。相反，在特定的自由度的基本规律和规则已被发现，并成功地应用于各种问题。这意味着在核物理中有几个层次：夸克和胶子，强子，原子核和核物质。相应地，在每个层次或连接层次中有几种类型的研究：
Nuclear physics aims at elucidating properties and dynamics of quantum many-body system composed of particles interacting via strong interaction, i.e., hadrons, quarks and gluons. Although the elementary theory for this field is Quantum Chromodynamics (QCD), it is not possible at present to apply QCD directly to actual problems in nuclear physics, which is mainly in non-perturbative regime of QCD. It is not possible at present to solve varous nuclear physics problems starting from bare realistic nucleon-nucleon interaction, too. Instead, basic laws and rules in specified degrees of freedom have been found and successfully applied to various problems. It means that there are several hierarchies in nuclear physics; quarks and gluons, hadrons, nuclei, and nuclear matter. Correspondingly, there are several types of research in each hierarchy or connecting hierarchies:
