Abstract: (Elsevier)
We investigate the constraints which muon decay experiments impose on the existence of light scalar neutrinos. If the s-neutrino masses are small compared to the muon mass, the charged wino has to be substantially heavier than the charged W-vector boson. From the existing measurements of the decay parameters ϱ and δ we find M W ̃ /M W > 4 . This bound can be improved by almost a factor of 2 by current experiments.- POSTULATED PARTICLE: SNEUTRINO
