摘要:

本文对用带电轻子和中微子散射实验测量的铁的结构函数F2的国际数据进行了比较研究。带电轻子和中微子散射的结果的一致性观察到的完整的全球数据集的价制度。一致性也观察到在低x的各种中微子数据集,以及带电轻子数据集,独立。然而,来自两个探针的数据在遮蔽/反遮蔽过渡区域中表现出15%的数量级的差异,其中Bjorken标度变量x < 0.15。这一观察结果表明,核子结构的中微子探针可能比带电轻子探针对不同的核效应敏感。此处提供了数据比较的详细信息和结果。

英文摘要:

A comparison study of world data for the structure function F2 for Iron, as measured by both charged lepton and neutrino scattering experiments, is presented. Consistency of results for both charged lepton and neutrino scattering is observed for the full global data set in the valence regime. Consistency is also observed at low x for the various neutrino data sets, as well as for the charged lepton data sets, independently. However, data from the two probes exhibit differences on the order of 15% in the shadowing/anti-shadowing transition region where the Bjorken scaling variable x is < 0.15. This observation is indicative that neutrino probes of nucleon structure might be sensitive to different nuclear effects than charged lepton probes. Details and results of the data comparison are here presented.
