方法：采用Giessen-Boltzmann-Uehling-Uhlenbeck （GiBUU）实现的量子动力学输运理论，改进了其对核基态和2p2h相互作用的处理。对于后者，采用电子散射数据的经验结构函数作为基础。结果：给出了电子诱导包涵截面的结果，作为该方法整体质量的必要检查。计算出的中微子诱导的双微分截面显示了MiniBooNE和T2K上不同中微子口味的中微子和反中微子反应的良好一致性数据。给出了MicroBooNE、NOvA、MINERvA和LBNF/DUNE的包容性双微分截面。结论：基于GiBUU轻子-核相互作用模型，现在可以很好地从理论上描述大范围能量、不同中微子口味和不同实验下的电子、中微子和反中微子-核数据。由于不涉及调谐，该理论和代码也应该是可靠的新能源制度和目标质量。
Methods: The Giessen-Boltzmann-Uehling-Uhlenbeck (GiBUU) implementation of quantum-kinetic transport theory is used, with improvements in its treatment of the nuclear ground state and of 2p2h interactions. For the latter an empirical structure function from electron scattering data is used as a basis. Results: Results for electron-induced inclusive cross sections are given as a necessary check for the overall quality of this approach. The calculated neutrino-induced inclusive double-differential cross sections show good agreement data from neutrino- and antineutrino reactions for different neutrino flavors at MiniBooNE and T2K. Inclusive double-differential cross sections for MicroBooNE, NOvA, MINERvA and LBNF/DUNE are given. Conclusions: Based on the GiBUU model of lepton-nucleus interactions a good theoretical description of inclusive electron-, neutrino- and antineutrino-nucleus data over a wide range of energies, different neutrino flavors and different experiments is now possible. Since no tuning is involved this theory and code should be reliable also for new energy regimes and target masses.
