Radiation Reaction and the Electromagnetic Energy-Momentum of Moving Relativistic Charged Membranes
Abstract
The charged membrane of Dirac provides a stable electron model with finite self energy. Its total mass $m$ has been previously calculated from the Hamiltonian of the membrane. To complete the picture we evaluate it here on the basis of the energy-momentum of its self field (radiation reaction) and obtain the same result showing the consistency of the model. We show explicitly that the old 4/3-problem does not arise. The electron's stability (the vanishing of total ${T^{μν}}_{, ν}$) is due to surface tension $κ$ of the membrane, but the model is as simple as the point particle, with two parameters $κ$ and $e$; the surface tension parameter $κ$ can be expressed in terms of the mass $m$.
