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.

在加拿大的Triumf实验室将进行核子上捕获和乳头捕获的测量。实验的目标是探索这些基本过程的反应动力学，并探索潜在的耐药性能，例如核子的轴向外形，诱导的伪尺度耦合以及带电的尖端电动极化性。这些结果将提供手性扰动理论的测试。另外，将研究对核对核的捕获，以研究核培养基对有效伪内偶联的影响。
