The MINERvA collaboration reports a novel study of neutrino-nucleus charged-current deep inelastic scattering (DIS) using the same neutrino beam incident on targets of polystyrene, graphite, iron, and lead. Results are presented as ratios of C, Fe, and Pb to CH. The ratios of total DIS cross sections as a function of neutrino energy and flux-integrated differential cross sections as a function of the Bjorken scaling variable x are presented in the neutrino-energy range of 5 - 50 GeV. Good agreement is found between the data and predicted ratios, based on charged-lepton nucleus scattering, at medium x and low neutrino energies. However, the data rate appears depleted in the vicinity of the nuclear shadowing region, x < 0.1. This apparent deficit, reflected in the DIS cross-section ratio at high neutrino energy , is consistent with previous MINERvA observations and with the predicted onset of nuclear shadowing with the the axial-vector current in neutrino scattering.
Partonic Transverse Motion in Unpolarized Semi-Inclusive Deep Inelastic Scattering Processes
分析了部分子横向运动在非极化半包容深度非弹性散射（SIDIS）过程中的作用。施加适当的运动学条件，我们发现一些限制，固定的上限范围内允许的k_perp值。我们表明，应用这些额外的要求的部分子运动学，我们得到不同的结果相对于通常的唯象方法的基础上的高斯涂抹与分析积分在无限范围内的k_perp值。这些变化对某些观测值特别有意义，例如< cos phi_h >未极化SIDIS截面的方位角调制或最终检测到的强子的平均横向动量。

Energy Flow in the Hadronic Final State of Diffractive and Non-Diffractive Deep-Inelastic Scattering at HERA
本文研究了HERA衍射和非衍射电子-质子深度非弹性散射中的强子末态，其中衍射数据是通过要求质子残余方向附近的赝快度有一个大的间隙来实验选择的。在强子末态的横向能量流的评估使用一组量化的拓扑性质的估计。使用现有的Monte Carlo QCD计算，它表明，衍射DIS中的最终状态表现出预期的功能，如果相互作用被解释为电子的散射离开当前夸克与微扰QCD的相关影响。一个模型，其中深-非弹性衍射被视为交换的pomeron与部分结构被发现重现的测量。深非弹性$ep$散射模型，其中一个相当大的衍射贡献是目前，因为非微扰效应在生产的强子最终状态，复制的数据的一般趋势，但在所有给一个更糟糕的描述。
