固体和液体靶上中微子散射的集体效应
Collective effects in neutrino scattering on solid and liquid targets
摘要：
在低能转移下，中微子在液体和固体目标上的散射既可以作为研究标准模型之外的物理的工具，例如，中微子电磁相互作用，也可以作为低能尺度下标准模型的测试。与此同时，低能弹性中微子散射在液体和固体中的电子和原子核上的理论装置必须考虑到目标的电子和原子核子系统中的集体效应。我们开发了这样一个装置的动态结构因子的形式主义的基础上。的集体效应的作用的数值说明的情况下提供的超流He-4目标。
英文摘要：
Neutrino scattering on liquid and solid targets at low energy transfer can serve both as a tool for searching the physics beyond the Standard Model, for example, such as neutrino electromagnetic interactions, and as a test of the Standard Model at low-energy scale. At the same time, the theoretical apparatus for low-energy elastic neutrino scattering on electrons and nuclei bound in liquids and solids must take into account collective effects in the electron and nuclear subsystems of the target. We develop such an apparatus based on the formalism of the dynamic structure factor. A numerical illustration of the role of the collective effects is provided for the case of a superfluid He-4 target.
