THE NEUTRINOS — SCHWARTZ 367 



experiment has some events which could be interpreted as the pro- 

 duction of such a particle. The boson is expected to live for only 

 about 10"" seconds before decaying, and can only be detected by 

 means of its decay products ( which should include electrons, or muons, 

 along with their respective neutrinos). An event could then be 

 characterized, for example, by the appearance of two muons — one, 

 the primary muon, and the other resulting from the decay of the boson. 

 Finally, one may hope that future neutrino physics will yield 

 sufficient data about the weak interactions at high energies to lead to 

 a comprehensive theory of these interactions. One may even hope 

 to shed some light on the basic difference between the electron and the 

 muon which, in some way, should be related to the difference between 

 their respective neutrinos. At any rate, the future of neutrino physics 

 seems quite exciting.
