9402462 Gorringe Fundamental properties of the electro-weak interaction will be measured via the muon-nucleon capture reaction. Specifically, coupling constants for the various components of the interaction in nuclear systems are not known well enough to constrain theory. In addition, medium effects may alter the strong interaction correction to the elemental interaction via meson exchange currents, isobar excitations, and nucleon structure. Correspondingly, muon capture measurements will be carried out in hydrogen and in complex nuclei, as well as needed ancillary experiments. This work will be done at the TRIUMF lab in Canada. ***

9402462 Gorringe 电弱相互作用的基本性质将通过μ子-核子捕获反应进行测量。 具体来说，核系统中相互作用的各个组成部分的耦合常数尚不清楚，不足以限制理论。 此外，介质效应可能会通过介子交换电流、等压线激发和核子结构来改变对元素相互作用的强相互作用校正。 相应地，μ子捕获测量将在氢和复杂原子核中进行，以及所需的辅助实验。 这项工作将在加拿大的 TRIUMF 实验室完成。 ***
