Abstract

The V-A structure of the weak interaction was put into the standard model by hand in order to obtain agreement with experiments; These experiments, however, do not rule out relatively large deviations from this structure. Muon decay provides an ideal laboratory to test this structure, being a purely leptonic process. TRIUMF experiment E614 will measure both the energy andemission-angle distribution of positrons from the decay of polarized muons. This will provide a simultaneous determination of the Michel parameters P(mu)xi rho and delta describing muon decay with a precision of a few pacts in 10(4). Stringent limits may then be placed on the coupling constants, aswell as the mass and mixing angle of a possible right-handed W boson (W-R). In this paper the formalism for muon decay is presented, the E614 experiment is described, and the sensitivity expected from E614 is compared to present limits on the values of the coupling constants and the mass and mixingangle of W-R.
