In $\nu /\bar{\nu }$–nucleon/nucleus interactions shallow inelastic scattering (SIS) is technically defined in terms of the four-momentum transfer to the hadronic system as non-resonant meson production with Q 2 ⪅ 1GeV2. This non-resonant meson production intermixes with resonant meson production in a regime of similar effective hadronic mass W of the interaction. As Q 2 grows and surpasses this ≈1GeV2 limit, non-resonant interactions begin to take place with quarks within the nucleon indicating the start of deep inelastic scattering (DIS). To essentially separate this resonant plus non-resonant meson production from DIS quark-fragmented meson production, a cut of 2 GeV in W of the interactions is generally introduced. However, since experimentally mesons from resonance decay cannot be separated from non-resonant produced mesons, SIS for all practical purposes in this review has been defined as inclusive meson production that includes non-resonant plus resonant meson production and the interference between them. Experimentally then for W ⪅ 2 GeV inclusive meson production with W ⪆ (M N + M π ) and all Q 2 is here defined as SIS, while for W ⪆ 2 GeV, the kinematic region with Q 2 ⪆ 1GeV2 is defined as DIS. The so defined SIS and DIS regions have received varying degrees of attention from the community. While the theoretical/phenomenological study of ν–nucleon and ν–nucleus DIS scattering is advanced, such studies of a large portion of the SIS region, particularly the SIS to DIS transition region, have hardly begun. Experimentally, the SIS and the DIS regions for ν–nucleon scattering have minimal results and only in the experimental study of the ν–nucleus DIS region are there significant results for some nuclei. Since current and future neutrino oscillation experiments have contributions from both higher W SIS and DIS kinematic regions and these regions are in need of both considerable theoretical and experimental study, this review will concentrate on these SIS to DIS transition and DIS kinematic regions surveying our knowledge and the current challenges.

浅弹性和深弹性散射区域中的中微子(反中微子)-核相互作用

$ \ nu / \ bar {\ nu} $-nucleon /核相互作用浅非弹性散射(SIS)是在四动量传递到强子系统作为非共振介子与生产方面在技术上定义Q 2 ⪅1GeV 2。在相互作用的类似有效强子质量W的情况下,该非共振介子产生与共振介子产生混合。作为Q 2的增长并超过此≈1GeV 2限制,非谐振的相互作用开始发生与核子指示深非弹性散射(DIS)的起始内夸克。为了将共振和非共振介子的产生与DIS夸克碎片介子的产生基本区分开,在W中削减了2 GeV通常介绍交互作用。但是,由于实验上无法将共振衰减的介子与非共振产生的介子分开,因此在本综述中,出于所有实际目的,SIS被定义为包容性介子产生,包括非共振加共振介子产生以及它们之间的干扰。实验然后W¯¯ ⪅2 GeV的包容介子生产与W¯¯ ⪆(中号 Ñ +中号π)和所有Q 2在这里定义为SIS,而对于W¯¯ ⪆2 GeV的,与所述运动区域Q 2 ⪆1GeV 2 被定义为DIS。如此定义的SIS和DIS区域受到了社区的不同程度的关注。虽然理论/现象学研究ν -nucleon和ν -nucleus DIS散射先进,SIS区域的大部分的这种研究,特别是对SIS DIS过渡区域,几乎没有开始。在实验中,SIS并为DIS地区ν -nucleon散射具有最小的结果,只有在的实验研究ν -nucleus DIS区域是有一些核显著成果。由于当前和未来的中微子振荡实验都受到较高W的影响 SIS和DIS运动学区域以及这些区域都需要大量的理论和实验研究,本文将重点考察这些SIS向DIS过渡和DIS运动学区域,以调查我们的知识和当前面临的挑战。
