TL;DR: In this paper, the authors evaluate the limits for anisotropic μ+→e+X0 decays, which can arise from interactions violating both lepton flavor and parity conservation.

TL;DR: A simultaneous measurement of the muon decay parameters ρ, δ, and P(μ)(π)ξ tests the standard model in a purely leptonic process and provides improved limits for relevant extensions to thestandard model.

TL;DR: In this article, the TWIST collaboration measured the muon decay parameter δ = 0.74964{+-}0.00066(stat.){+ − 0.00112(syst.), consistent with the standard model value of 3/4.

TL;DR: In this article, a new high precision measurement of parity violation in the weak interaction, using polarized muon decay, was presented, where the TWIST Collaboration has measured the parity violation of weak interaction.

TL;DR: In this article, the authors measured the degree of muon polarization in pion decay and obtained a value P{sub {mu}}{sup {pi}}{xi}=1.0003{+-}0.0006(stat.){+ − 0.0038(syst.) was obtained.
