氩、碳和钛上包容电子散射的平均场和两体核效应：超标度方法
Mean field and two-body nuclear effects in inclusive electron scattering on argon, carbon and titanium: the superscaling approach
摘要：
我们比较了SuSAv2模型的预测，包括两个粒子两个空穴介子交换电流与最近的JLab数据包容电子散射三个不同的目标（C，Ar和Ti）。协议是非常好的，在整个能量谱，只有在深非弹性区域看到一些差异。在准弹性和$Δ$共振峰之间的倾斜区域达到峰值的2p2h响应对于再现数据是必不可少的。我们还分析了$k_F$（费米动量）的依赖性的数据在第二类标度，表明2p2h响应标度非常不同的准弹性的，完全符合什么是预测的模型。结果代表了一个有价值的测试模型的适用性中微子在不同的核散射过程。
英文摘要：
We compare the predictions of the SuSAv2 model including two-particle two-hole meson-exchange currents with the recent JLab data for inclusive electron scattering on three different targets (C, Ar and Ti). The agreement is very good over the full energy spectrum, with some discrepancy seen only in the deep inelastic region. The 2p2h response, peaked in the dip region between the quasielastic and $Δ$-resonance peak, is essential to reproduce the data. We also analyze the $k_F$ (Fermi momentum) dependence of the data in terms of scaling of second kind, showing that the 2p2h response scales very differently from the quasielastic one, in full accord with what is predicted by the model. The results represent a valuable test of the applicability of the model to neutrino scattering processes on different nuclei.
