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.

The Copley Medal is awarded to Professor A. Salam, K.B.E., F.R.S., in recognition of his work on the symmetries of the laws of nature, and especially the unification of the electromagnetic and weak forces. Professor Salam has made outstanding and influential contributions to elementary particle theory over a period of 40 years. His early work included the completion of Dyson's proof of the renormalization of quantum electrodynamics, and his work on parity violation, dispersion relations and SU(3) invariance. This work contributed greatly to the development of elementary particle theory, but his major contribution was the proposal, in parallel with S. Weinberg, of the electroweak theory, unifying quantum electrodynamics with the weak interactions between atomic particles. That theory, the first to bring together the theories of the atomic forces, received spectacular confirmation through the discovery at CERN in 1983 of W + and Z intermediate bosons.
