Keywords: Electron self energy.svg Electron self energy contribution This is the one-loop contribution to the electron one particle irreducible function which in turn affects the electron self-energy function Σ This leads to a shift in the mass of the electron Essentially this measures how much mass an electron gains via the electromagnetic field it generates around it Original raster version created by Phys SVG created by dnet en wikipedia Sreejithk2000 CommonsHelper 2007-09-16 DnetSvg wikipedia en 100px DnetSvg original upload log page en wikipedia Electron_self_energy svg 2007-09-16 17 16 DnetSvg 151×50× 2512 bytes <nowiki> Electron self energy contribution This is the one-loop contribution to the electron one particle irreducible function which in turn affects the electron self-energy function Σ This leads to a shift in the mass of th</nowiki> Quantum electrodynamics Feynman diagrams |
