About the Quantum Fields Theory

Abstract

In QFT the potentials are put in a complex form with the association $\hbar \,i \hbox{ of } \hbar$ with the number $i=\sqrt{-1}$ by analogy with the presence of $\hbar i$ in the Dirac equation. But in this equation i has in fact the meaning of a real bivector of space-time which has no place in an electromagnetic potential. The results are the same as a real quantum electrodynamics because, in the calculations, the imaginary parts of these potentials are null. But when the potential is in the form q/R, the QFT construction leads to the presence of an unacceptable nonsense.
