A New Look at the Higgs-Kibble Model

An elementary perturbative method of handling the Higgs-Kibble models and deriving their relevant properties, is described. It is based on Wightman field theory and avoids some of the mathematical weaknesses of the standard treatments.Comment: Based on a talk delivered at the `Ringberg Symposium' in honor of Wolfhart Zimmermann, February 200

What is the Magnetic Moment of the Electron?

A direct definition of the intrinsic magnetic moment of the electron is given, which does not use infrared regularizations and interactions with external fields. The expression does not depend on the unavoidable ambiguities of the definition of a 1-electron state (exact form of its soft photon cloud). The method leads to the same analytic expression as the conventional approach, thus preserving the excellent agreement between theory and experiment.Comment: 24 pages, 4 figures, uses axodraw.st
