Spinor electrodynamics in the Riemann-Cartan space and dynamical theory of axial vector torsion propagating in vacuum

Abstract

In the Riemann-Cartan space we develop a gravitational theory of spinor electrodynamics, making torsion propagate in vacuum. Prom the precision experiment we can deduce the torsion coupling constant divided by the mass,f2/4πμ2< 10−5 (GeV)−2, for ώ≪mα and ώ≫mα, where m is the electron mass and α is the fine-structure constant. It is interesting to inquire if there is a new interaction.
