L. Alvarez-Ruso, Y. Hayato, J. Nieves

摘要:

中微子截面的新的和更精确的测量重新引起了人们对更好地理解核子和原子核上的电弱相互作用的兴趣。这一努力对于实现中微子振荡计划的精确目标至关重要,使新的发现成为可能,如轻子区的CP破坏。本文综述了中微子截面物理的最新进展,着重讨论了在与新的实验数据进行比较时出现的问题。在概述了最近的中微子实验和未来的计划,我们提出了一些详细的理论发展的描述(反)中微子诱导的准弹性散射和多核子准弹性机制的作用。我们不仅讨论了核子和原子核中的π介子产生,还讨论了其它非弹性通道,包括奇异值产生和光子发射。还讨论了核靶上的相干反应通道。最后,我们简要地描述了一些蒙特卡罗事件发生器,这是在所有的中微子振荡和截面测量的核心。

英文摘要:

New and more precise measurements of neutrino cross sections have renewed the interest in a better understanding of electroweak interactions on nucleons and nuclei. This effort is crucial to achieve the precision goals of the neutrino oscillation program, making new discoveries, like the CP violation in the leptonic sector, possible. We review the recent progress in the physics of neutrino cross sections, putting emphasis on the open questions that arise in the comparison with new experimental data. Following an overview of recent neutrino experiments and future plans, we present some details about the theoretical development in the description of (anti)neutrino-induced quasielastic scattering and the role of multi-nucleon quasielastic-like mechanisms. We cover not only pion production in nucleons and nuclei but also other inelastic channels including strangeness production and photon emission. Coherent reaction channels on nuclear targets are also discussed. Finally, we briefly describe some of the Monte Carlo event generators, which are at the core of all neutrino oscillation and cross section measurements.
