在这篇综述中，我们首先概述了运输理论的基础，以及它对脱壳运输的最新推广。然后，我们以Giessen Boltzmann-Uehling-Uhlenbeck(GiBUU)这一理论的实现为例，详细介绍了任何传输方法的主要成分。我们讨论了所使用的势、基态初始化和碰撞项，包括后者的媒质修正。这篇综述的中心部分涵盖了GiBUU在一大类反应中的应用，从质子上的介子诱导反应和原子核上的反质子反应到重离子碰撞(高达30AGeV)。主要部分还涉及对光子、电子和中微子诱导的反应(能量范围从几个100 MeV到几个100GeV)的描述。对于这一大类反应，GiBUU用相同的物理输入和使用的相同代码进行了出色的描述。我们认为，GiBUU对于研究末态相互作用起作用的任何核反应都是不可或缺的工具。研究介子-核相互作用、核碎裂、重离子反应、超核形成、强子化、色透明、电子-核碰撞和中微子-核相互作用都是GiBUU的可能应用，本文对此进行了讨论。
In this review we first outline the basics of transport theory and its recent generalization to off-shell transport. We then present in some detail the main ingredients of any transport method using in particular the Giessen Boltzmann–Uehling–Uhlenbeck (GiBUU) implementation of this theory as an example. We discuss the potentials used, the ground state initialization and the collision term, including the in-medium modifications of the latter. The central part of this review covers applications of GiBUU to a wide class of reactions, starting from pion-induced reactions over proton and antiproton reactions on nuclei to heavy-ion collisions (up to about 30AGeV). A major part concerns also the description of photon-, electron- and neutrino-induced reactions (in the energy range from a few 100MeV to a few 100GeV). For this wide class of reactions GiBUU gives an excellent description with the same physics input and the same code being used. We argue that GiBUU is an indispensable tool for any investigation of nuclear reactions in which final-state interactions play a role. Studies of pion–nucleus interactions, nuclear fragmentation, heavy-ion reactions, hypernucleus formation, hadronization, color transparency, electron–nucleus collisions and neutrino–nucleus interactions are all possible applications of GiBUU and are discussed in this article.
