The quest for purely virtual quanta: fakeons versus Feynman-Wheeler particles
Abstract The search for purely virtual quanta has attracted interest in the past. We consider various proposals and compare them to the concept of fake particle, or “fakeon”. In particular, the Feynman-Wheeler propagator, which amounts to using the Cauchy principal value inside Feynman diagrams, vio...
