What I have to say will consist largely of speculation, because no unusual feature of muon interactions at high energies has yet been established. Considerable efforts have been made in the last few years to find an anomalous effect, but so far the result has been negative. This is probably because we have not yet reached high enough energies, as will become evident during the course of this talk. Figure 19 shows a number of possible interactions of the muon, which will be considered in detail below. There is first the electromagnetic coupling to the photon, with coupling constant e satisfying e 2 = 1/137 (figure 19( a )). Figure 19( b ) shows the weak interaction coupling, to the intermediate boson W ± (which is here assumed to exist). To obtain the correct strength for the overall weak four-fermion interaction one requires g 2 / m 2 w = G weak = 10 -5 / m 2 N , where m N is the nucleon mass. Thus only the ratio of g 2 to m 2 w is fixed.

Difficult Subject

The subject I am supposed to report on is intermediate bosons and unitary symmetry. This is a difficult subject for two reasons. The first is that there is at the present time no experimental evidence at all that these bosons really exist. The second one is that, even if they exist, we do not know whether they have really something to do with unitary symmetry. These are serious objections, especially the first. The reason why, in spite of it, I still want to give this talk is the following. Most theoretical physicists believe, I think, that we cannot live for ever with the weak interactions just being described by effective Fermi coupling constants and the like.
