The present status of the field theoretical model studies of the deep inelastic scattering induced by (anti)neutrino on the nuclear targets in a wide range of Bjorken variable x and four momentum transfer square \(Q^2\) has been reviewed (Haider et al. in Phys Rev C 84:054610, 2011, Phys Rev C 85:155201, 2012, Nucl Phys A 955:58, 2016; Zaidi et al. in Phys Rev D 99:093011, 2019, Phys Rev D 101:033001, 2020; Ansari et al. in Phys Rev D 102:113007, 2020). The effect of the nonperturbative corrections such as target mass corrections and dynamical higher twist effects, perturbative evolution of the parton densities, nuclear medium modifications in the nucleon structure functions, and nuclear isoscalarity corrections on the weak nuclear structure functions have been discussed. These structure functions have been used to obtain the differential scattering cross-sections. The various nuclear medium effects such as the Fermi motion, binding energy, nucleon correlations, mesonic contributions, shadowing and antishadowing corrections relevant in the different regions of x and \(Q^2\) have been discussed. The numerical results for the structure functions and the cross-sections are compared with some of the available experimental data including the recent results from MINERvA. The predictions are made in argon nuclear target which is planned to be used as a target material in DUNE at the Fermilab.

深非弹性(反)中微子核散射

大范围Bjorken变量x和四动量传递平方\(Q^2\)下(反)中微子对核目标引起的深非弹性散射场理论模型研究现状(Haider et al. in Phys Rev C 84:054610, 2011, Phys Rev C 85:155201, 2012, Nucl Phys A 955:58, 2016; Zaidi et al. in Phys Rev D 99:092019, 2011 Phys Rev D 101:033001, 2020;Ansari et al. in Phys Rev D 102:113007, 2020)。讨论了非微扰校正的影响,例如目标质量校正和动态更高的扭曲效应、部分子密度的微扰演化、核子结构函数中的核介质修改以及核等标校正对弱核结构函数的影响。这些结构函数已被用于获得微分散射截面。各种核介质效应,例如费米运动、结合能、核子相关性、介子贡献、与不同区域相关的阴影和反阴影校正x\(Q^2\)已经讨论过了。结构函数和横截面的数值结果与一些可用的实验数据进行了比较,包括来自 MINERvA 的最新结果。预测是在氩核目标中进行的,该目标计划用作费米实验室 DUNE 中的目标材料。
