Derivation of strong and weak forces from magnetic interactions in quantum electrodynamics (QED)

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.

Classical Radiation

A manifestly gauge invariant relativistic quantum field theory of the interaction of atomic systems with electromagnetic fields is shown to be systematically obtained from conventional quantum electrodynamics. The basic ingredient is an exact decomposition of the Dirac sources J μ modified to include the binding, into polarization sources P and M . The transformation of the conventional theory is achieved by means of a generalized Power-Zienau-Woolley transformation. While J μ couple to the potentials A μ , the polarization sources are shown to couple directly to the field intensities E and B . An explicit separation between electric and magnetic interactions is thus obtained which is in close correspondence w'ith the case in the semi-classical radiation theory. The relevance of the transformed theory to problems involving intense electromagnetic fields is pointed out and discussed.
