Precision experiments with pions and muons

Oral

The Fermi constant $G_\mathrm{F}$ governs the rates of all weak interaction processes and, along with the fine structure constant $\alpha$ and the $Z$-boson mass $M_Z$, it is one of the principal input parameters to the Standard Model. Owing to the purely leptonic nature of the muon decay process, $G_\mathrm{F}$ is extracted most precisely from measurements of the muon lifetime...

Precision experiments with pions and muons

Oral

The current theoretical and experimental status for muon captures on light nuclei will be reviewed. In particular, a new theoretical study of muon captures on deuteron and 3He will be presented, in which realistic potentials and consistent weak currents are used, and it will be shown that it is possible to reduce the model dependence relative to the adopted interactions and currents at the...
