Abstract

The concept of coherence in the scattering of neutrinos and antineutrinos off nuclei is discussed. Motivated by the results of the COHERENT experiment, a new approach to coherence in these processes is proposed, which allows a unified description of the elastic (coherent) and inelastic (incoherent) contributions to the total cross section for neutrino and antineutrino scattering off nuclei at energies below 100 MeV. Experiments and physical problems for coherent scattering of (anti)neutrinos off nuclei are briefly discussed. The extended appendix covers the main points and conclusions of the proposed approach in pedagogical detail.

中微子和反中微子从核中散射的相干概念

摘要

讨论了中微子和反中微子从原子核的散射中的相干性概念。受相干实验结果的启发，提出了一种在这些过程中相干的新方法，该方法可以统一描述中微子和反中微子在原子核外散射时对总横截面的弹性（相干）和非弹性（非相干）贡献。能量低于100 MeV。简要讨论了（反）中微子从原子核相干散射的实验和物理问题。扩展的附录详细介绍了该方法的要点和结论。
