Determination of the Muon Decay Parameters

Abstract

The investigation of the purely leptonic decay μ⁺e⁺υ_eū_μ of the muon is of fundamental interest since it allows to put constraints on theories of weak interactions. To improve our present-day knowledge about charged weak interactions it is necessary both to measure the decay parameters with high precision and to make full use of the mutual interdependence of the decay parameters yielding additional constraints.
