The weak coupling constant, $G_F,$ is determined most precisely from the mean life of the positive muon, $\tau_\mu$. Advances in theory have reduced the theoretical uncertainty on $G_F$ as calculated from $\tau_\mu$ to a few tenths of a ppm. The remaining uncertainty on $G_F$ is entirely experimental, and is dominated by the uncertainty on $\tau_\mu$. The MuLan experiment is designed...

Muon decay offers an opportunity to test the Standard Model of particle physics in a purely leptonic low-energy situation where more ambiguous strong interaction processes are essentially absent. The TRIUMF Weak Interaction Symmetry Test (TWIST) was designed specifically to improve by an order of magnitude the precision of the decay parameters rho, delta, and Pmu*xi derived from energy and...

The NEMO-3 detector aimed to study double beta (bb) decays in general and to search for neutrinoless mode (0nbb) particularly provides unique tracko-calorimetric technique able to register full bb-signature. This information is crucial for investigation of 0nbb-mechanism once 0nbb-decay will be discovered. Continuing to take data since February 2003 at the moment the NEMO-3 is the only...
