On the geometrization of the electro-magnetic interaction for a spinning particle

TL;DR

This paper demonstrates that in a Kaluza-Klein framework, both electromagnetic fields and the dynamics of charged spinning particles can be geometrized through a 5-dimensional spacetime approach.

Contribution

It extends the geometrization of electromagnetic interactions to include the dynamics of spinning particles within a 5D Kaluza-Klein model.

Findings

Electromagnetic fields can be geometrized in a 5D framework.

Charged spinning particle dynamics can be derived from 5D motion.

Dimensional splitting of Papapetrou equations is effective for this purpose.

Abstract

We outline that, in a Kaluza-Klein framework, not only the electro-magnetic field can be geometrized, but also the dynamics of a charged spinning particle can be inferred from the motion in a 5-dimensional space-time. This result is achieved by the dimensional splitting of Papapetrou equations and by proper identifications of 4-dimensional quantities.
