An interaction of a pseudoscalar particle with two photons induced by an external electromagnetic field is used to study the photon decay γ → γa where a is a pseudoscalar particle associated with the Peccei-Quinn U(1) symmetry. The fieldinduced axion emission by photon is analyzed as a possible source of energy losses by astrophysical objects.

A unified and fully relativistic treatment of the interaction of the electric and magnetic dipole moments of a particle with the electromagnetic field is given. New forces on the particle due to the combined effect of electric and magnetic dipoles are obtained. Several new experiments are proposed, which include observation of topological phase shifts.

In nuclear physics, it is well known that the electromagnetic (Coulomb) interaction between final state products can drastically effect particle reaction rates. Near thresholds, for example, nuclear alpha decay is suppressed while nuclear beta decay is enhanced by final state Coulomb interactions. Here we discuss high energy physics enhancement and/or suppression of reactions wherein the potent...

This Resource Letter provides a guide to literature on the Standard Model of elementary particles and possible extensions. In the successful theory of quarks and leptons and their interactions, important questions remain, such as the mechanism of electroweak symmetry breaking, the origin of quark and lepton masses, the source of the baryon asymmetry of the Universe, and the makeup of its matter...

Whenever real particle production occurs in quantum field theory, the imaginary part of the Hadamard Elementary function G(1) is non-vanishing. A method is presented whereby the imaginary part of G(1) may be calculated for a charged scalar field in a static spherically symmetric spacetime with arbitrary curvature coupling and a classical electromagnetic field Aμ. The calculations are performed ...
