Born renormalization in classical Maxwell electrodynamics

[摘要] We define and compute the renormalized four-momentum of the composed physical system: classical Maxwell field interacting with charged point particles. As a 'reference' configuration for the field surrounding the particle, we take the Born solution. Unlike in the previous approach [Commun. Math. Phys. 198 (1998) 711; Gen. Relat. Grav. 26 (1994) 167; Acta Phys. Pol. A 85 (1994) 771], based on the Coulomb 'reference', a dependence of the four-momentum of the particle ('dressed' with the Born solution) upon its acceleration arises in a natural way. This will change the resulting equations of motion. Similarly, we treat the angular momentum tensor of the system. (C) 2003 Elsevier Science B.V. All rights reserved.
