论文摘要
我们已经对中微子的性质及其与物质的相互作用进行了回顾。讨论了不同的(抗)中微子过程,例如准散射,介子和超子的非弹性产生,以及来自游离核子的深度非弹性散射,并提供了散射横截面的结果。还研究了在最终状态下产生的瘦小和辐射的极化(在绝对散射的情况下)。在上述过程中,核培养基效应在低,中间和高能区域以及相干中微子核散射,相干的介子产生和三叉戟产生的过程中的重要性得到了强调。在某些情况下,还给出了横截面的结果,并将其与可用的实验数据以及不同理论模型中的预测进行了比较。这项研究将有助于理解(反)中微子相互作用横截面与与下一代实验有关的少数GEV能量区域中的物质,例如沙丘,超级kamiokande,以及其他与加速器和大气中微子相关的实验。我们强调需要在研究核中研究核培养基效应的某些过程中需要更好的理论模型。
We have presented a review of the properties of neutrinos and their interactions with matter. The different (anti)neutrino processes like the quasielastic scattering, inelastic production of mesons and hyperons, and the deep inelastic scattering from the free nucleons are discussed and the results for the scattering cross sections are presented. The polarization observables for the leptons and hadrons produced in the final state, in the case of quasielastic scattering, are also studied. The importance of nuclear medium effects in the low, intermediate and high energy regions, in the above processes along with the processes of the coherent neutrino-nucleus scattering, coherent meson production, and trident production, have been highlighted. In some cases the results of the cross sections are also given and compared with the available experimental data as well as with the predictions in the different theoretical models. This study would be helpful in understanding the (anti)neutrino interaction cross section with matter in the few GeV energy region relevant to the next generation experiments like DUNE, Hyper-Kamiokande, and other experiments with accelerator and atmospheric neutrinos. We have emphasized the need of better theoretical models for some of these processes for studying the nuclear medium effects in nuclei.
