Abstract
New limits are reported on right-handed currents, based on precise measurement of the spectrum end point in decay. Highly polarized muons from the TRIUMF "surface" beam were stopped in metal foils within a 1.1-T spin-holding longitudinal field or a 70-G spin-precessing transverse field. For the spin-held data, the decay rate vanishes in the beam direction at the end point. Measurement of this rate sets the 90%-confidence limits and GeV, where is the possible righthanded gauge boson.
