the simplest possible muon decay scheme, taking into account conservatio n
laws, is
e + v i.. v . (4 .1 .4 )
However, we must be careful not to make the assumption that the neutrino an d
antineutrino on the right—hand side of the decay (4 .1 .4) are similar to thos e
which we studied in chapter 3 . As we shall see, they are, in fact, not similar .
A number of other muon decay modes have been suggested to date (5) :
Deca
Branching ratio
