The apparent absence of muon-electron transi-tions without neutrinos, such as p. e+ y, p. 3e,
and p+ p~ e+ p, leads one to suspect that there is a new conservation law forbiddingthem …

energetically and in every other known respect do not occur. In this note we shall indicate
how for a certain class of interactions which might be ex-pected to induce pe …

One of the familiar and puzzling properties of the muon is the apparent absence of the decay
p,«e+ y (unaccompanied by neutrinos), although it is not forbidden by any known selection …

Speculating on the possible existence of a strong muon-electron coupling which has
escaped observation because of a multiplicative muon conservation law, we have looked for …

The discovery that the neutrinos from pion-muon-neutrino (7r-J..!-v) decay are distinct from
the neutrinos of/3 decay has made it clear that a distinct class of particles exists which, so …

On the basis of the hypothesis that the same form of interaction acts among any spin-½
particles, it is interesting to apply the interaction law found for β decay to the muon …

An attempt is made to construct a theory of all weak processes from a single invariance
principle. The requirement that the weak interaction Hamiltonian be invariant under the …

'HK invited speakers have done an excellent job of describingthe various topics within the
field of weak interactions. The contributed papers have presented many fascinating results …

We consider the possibility that muon-number conservation is not a fundamental symmetry
of nature. In simple SU (2)⊗ U (1) gauge theories with several scalar boson doublets, muon …

Some processes due to free neutrinos which heretofore had not been considered are
discussed. Especial attention is given to those processes which in principle may help to …
