Eliminating Electron Self-repulsion

Problems of self-interaction arise in both classical and quantum field theories. To understand how such problems are to be addressed a theory the Dirac electromagnetic fields (quantum electrodynamics), we can start by analyzing these fields. In theory, electron has spread-out distribution charge that avoids some facing point models. However, there remains problem will experience self-repulsion. This self-repulsion cannot eliminated within without also losing Coulomb interactions between distinct particles. But, from electrodynamics gauge fully normal-ordering term Hamiltonian. After normal-ordering, contains pieces describing attraction repulsion particles particle creation annihilation, but no
