Sujet:	Tests of Lepton-flavor Conservation 

Par:	Dr.  A. van der Schaaf, Zurich University

Resume:	Lepton-flavor Conservation (LFC) is one of the corner stones of the 
	Standard Model, but may be violated in almost any extension of it. 
	By studying transitions between leptons from different generations, 
	one ultimately hopes to learn about the origin of the generation 
	structure itself. The status of laboratory tests of LFC will be 
	reviewed, with emphasis on LFC-violating ("forbidden") $\mu$ decays. 
	Ongoing searches with the two SINDRUM spectrometers at PSI will raise
	the present sensitivity by two to four orders of magnitude.
