论文摘要

密涅瓦报告了在NUMI光束线中的碳氢化合物上的MUON中微子的包含电动电流横截面。我们根据纵向和横向若子力量以及这些变量中的单差截面测量了双差横截面。此分析中使用的数据对应于目标上的$ 3.34 \ times 10^{20} $质子，峰值中微子能量约为3.5 GEV。将测量值与Genie，Nuwro和Gibuu Neutrino横截面预测进行了比较，以及一种修改的Genie版本，以与先前的独家密涅瓦测量结果更好地达成一致性。没有一个模型或变体能够在整个相位空间中成功地重现数据，其中包括每个相互作用通道主导的区域。

MINERvA reports inclusive charged-current cross sections for muon neutrinos on hydrocarbon in the NuMI beamline. We measured the double-differential cross section in terms of the longitudinal and transverse muon momenta, as well as the single-differential cross sections in those variables. The data used in this analysis correspond to an exposure of $3.34 \times 10^{20}$ protons on target with a peak neutrino energy of approximately 3.5 GeV. Measurements are compared to the GENIE, NuWro and GiBUU neutrino cross-section predictions, as well as a version of GENIE modified to produce better agreement with prior exclusive MINERvA measurements. None of the models or variants were able to successfully reproduce the data across the entire phase space, which includes areas dominated by each interaction channel.
