论文摘要
对于三种核模型的平面波脉冲近似，研究中微子核散射：相对论的费米气体（RFG），独立粒子壳模型（IPSM）和自然轨道（NO）模型，具有激发能的洛伦兹依赖性。对40 AR和12 C.综合横截面进行了对半包含过程和相关横截面的运动学的完整研究，也可以通过整合外卸下的半体表达式来获得。结果与以前仅限于包容性通道的研究一致。特别是，与RFG模型的分析结果进行了比较。给出了hadronic张量和10个半核反应的明确表达式。将理论预测与T2K实验的半包含实验数据进行了比较。
Neutrino-nucleus quasielastic scattering is studied in the plane wave impulse approximation for three nuclear models: the relativistic Fermi gas (RFG), the independent-particle shell model (IPSM) and the natural orbitals (NO) model with Lorentzian dependence of the excitation energy. A complete study of the kinematics of the semi-inclusive process and the associated cross sections are presented and discussed for 40 Ar and 12 C. Inclusive cross sections are also obtained by integrating the semi-inclusive expressions over the outgoing hadron. Results are consistent with previous studies restricted to the inclusive channel. In particular, a comparison with the analytical results for the RFG model is performed. Explicit expressions for the hadronic tensor and the 10 semi-inclusive nuclear responses are given. Theoretical predictions are compared with semi-inclusive experimental data from T2K experiment.
