Classical bremsstrahlung

›
In our March 17, 2021 blog post we analyzed the Wikipedia formula for bremsstrahlung and the Gaunt factor. There we looked at processes wher...

Electron-electron (Møller) scattering bremsstrahlung cross section

›
We want to find out what is the structure of the inner electric field of the electron, that is, the structure for a radius less than the ele...

A real photon self-energy Feynman diagram

›
On May 12, 2021 we analyzed the electron self-energy and concluded self-energy has no effect on a free (real) electron. Let us consider a re...

Photon-electron (Compton) scattering: a particle model of the photon

›
Let us analyze scattering of a high-energy photon from an electron. In previous blog posts we have stressed that we do not know the structur...

The electron self-energy Feynman diagram

›
In our December 19, 2020 blog post we remarked that the Feynman diagram for the electron self-energy seems to break conservation of the spee...

A new take on regularization of the vertex correction and bremsstrahlung

›
We have analyzed the vertex correction in  several blog posts in the past months. Let us try to form some kind of a synthesis. Classical ver...

If the energy of the field of the electron is infinite, then the electron plus the inner field has negative mass-energy

›
Let us write yet another post about the renormalization problem of a classical point charge. Suppose that an electron collides with a positr...
