Measurement of muon capture and pion capture on the nucleon will be carried out at the TRIUMF laboratory in Canada. The goals of the experiments are to explore reaction dynamics of these elementary processes and to explore the underlying hadronic properties, such as the nucleon's axial form factor, the induced pseudoscalar coupling, and the charged pion's electric polarizability. These results will provide tests of chiral perturbation theory. In addition muon capture on nuclei will be studied to study the effects of the nuclear medium on the effective pseudoscalar coupling.

将在加拿大的TRIUMF实验室测量核子上的μ子俘获和π介子俘获。实验的目的是探索这些基本过程的反应动力学，并探索潜在的强子性质，如核子的轴向形状因子，诱导的赝标耦合和带电π介子的电极化率。这些结果将为手征微扰理论提供检验。此外，我们还将研究μ子在核上的俘获，以研究核介质对有效赝标耦合的影响。
