Field Theory reformulated without self - energy parts . Classical electrodynamics
A manifestly gauge-invariant hamiltonian formulation [1] of classical electrodynamics has been shown to be relativistic invariant by the construction of the generators of the Poincare Lie algebra. The original formulation in terms of reduced distribution functions for the particles is applied here to the case of two charges interacting through the classical electrodynamical field. A reduced des...

متن کاملField Theory Reformulated without Self-energy Parts. the Dressing Operator
The reformulation of field theory for avoiding self-energy parts in the dynamical evolution has been applied successfully in the framework of the Lee model,[1] enabling a kinetic extension of the description. The basic ingredient is the recognition of these self-energy parts.[2] The original reversible description is embedded in the new one and appears now as a restricted class of initial condi...
متن کاملQuantum Field Theory without Divergence A
On the basis a new conjecture, we present a new Lagrangian density and a new quantization method for QED, construct coupling operators and mass operators, derive scattering operators Sf and Sw which are dependent on each other and supplement new Feynman rules. Sf and Sw together determine a Fenman integral. Hence all Feynman integrals are convergent and it is unnecessary to introduce regulariza...
متن کاملSingularity-Free Electrodynamics for Point Charges and Dipoles: Classical Model for Electron Self-Energy and Spin
It is shown how point charges and point dipoles with finite self-energies can be accomodated into classical electrodynamics. The key idea is the introduction of constitutive relations for the electromagnetic vacuum, which actually mirrors the physical reality of vacuum polarization. Our results reduce to conventional electrodynamics for scales large compared to the classical electron radius r0 ...
