对基本相互作用和对称性的精确研究和测试是现代粒子物理学的一个焦点。随着目前粒子物理学标准模型（SM）的成功，同时需要新的物理学来解决已知的缺陷，一个广泛的搜索计划正在进行中，以探索所有能量尺度的未知。精确测量的数量，可以准确地预测在SM，也特别是那些被预测为零或可忽略不计的小原来提供了一些最严格的约束，许多新的物理场景。除了一些弯路，本文集中在精密物理学使用中子，π介子和μ介子，最轻的不稳定粒子的种类，在最强大的质子加速器产生。
Precision studies and tests of fundamental interactions and symmetries are a focus point of modern particle physics. With the success of the present Standard Model (SM) of particle physics and simultaneously with the need for new physics to fix known deficiencies a broad search program is under way to probe at all energy scales for the unknown. Precision measurements of quantities which can be accurately predicted in the SM and also especially those which are predicted to be null or negligibly small turn out to provide some of the most stringent constraints for many new physics scenarios. Besides some detours, this paper concentrates on precision physics using neutrons, pions and muons, the lightest unstable particles of their kind, produced at the most powerful proton accelerators.
