## Quantum Field Theory with Electric-Magnetic Duality and Spin-Mass Duality But Without Grand Unification and Supersymmetry

**Authors:** Rainer W. Kühne

I present a generalization of quantum electrodynamics which includes Dirac
magnetic monopoles and the Salam magnetic photon. This quantum electromagnetodynamics
has many attractive features. (1) It explains the quantization
of electric charge. (2) It describes symmetrized Maxwell equations. (3) It is
manifestly covariant. (4) It describes local four-potentials. (5) It avoids the unphysical
Dirac string. (6) It predicts a second kind of electromagnetic radiation
which can be verified by a tabletop experiment. An effect of this radiation may
have been observed by August Kundt in 1885. Furthermore I discuss a generalization
of General Relativity which includes Cartan's torsion. I discuss the
mathematical definition, concrete description, and physical meaning of Cartan's
torsion. I argue that the electric-magnetic duality of quantum electromagnetodynamics
is analogous to the spin-mass duality of Einstein-Cartan theory. A
quantum version of this theory requires that the torsion tensor corresponds to
a spin-3 boson called tordion which is shown to have a rest mass close to the
Planck mass. Moreover I present an empirically satisfied fundamental equation
of unified field theory which includes the fundamental constants of electromagnetism
and gravity. I conclude with the remark that the concepts presented
here require neither Grand Unification nor supersymmetry.
