Abstract

The existence of a new fundamental interaction has long been discussed in literature, making it possible to extend the frames of Standard Model. In this work, the applicability of neutron scattering to the search for new internucleon short-range forces is analyzed for the interaction radius of 10^–8 < λ < 10^–13 m. The coupling constant constraints are obtained using the existing data on silicon powder diffraction from an instrument SPODI, FRM II, Germany. For interaction radius λ < 10^–11 m, these constraints are competitive with the best of the existing ones. The performance of a new experiment is expected to provide the constraints improvement of about two orders.

在中子散射中寻找新的核子间短程相互作用

摘要

在文献中早已讨论了新的基本交互作用的存在，从而有可能扩展标准模型的框架。在这项工作中，分析了中子散射在寻找新的核子间短程力方面的适用性，其相互作用半径为10 ^–8 <λ<10 ^–13 m。耦合常数约束条件是使用德国SRMDI仪器FRM II的现有硅粉衍射数据获得的。对于相互作用半径λ<10 – ¹¹ m，这些约束与现有约束中的最好的具有竞争性。新实验的性能有望提供约两个数量级的约束改进。
