Weak and Electromagnetic Interactions of Nucleons and Nuclei

对核子上的介子俘获和介子俘获的测量将在加拿大的TRIUMF实验室进行。这些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、诱导的赝标量耦合和带电介子的电极化率。这些结果将为手征微扰理论提供实验依据。此外，还将研究原子核上的Muon俘获，以研究核介质对有效伪标量耦合的影响。

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.
