Stefanovich E. Elementary Particle Theory. Volume 3: Relativistic Quantum Dynamics

2019. — de Gruyter, 2018. — 246 p. — (Studies in Mathematical Physics 47). — ISBN: 3110490900.In this third volume of three, quantum electrodynamics is formulated in the language of physical ?dressed" particles. A theory where charged particles interact via instantaneous action-at-a-distance forces is constructed - without need for renormalization. This theory describes electromagnetic phenomena in terms of directly interacting charges, but in full accord with fundamental principles of relativity and causality.Three ways to look at QFT
