On the geometrization of the electro-magnetic interaction for a spinning particle |
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 four-dimensional quantities. Then, since in such a context an electric dipole moment arises, we provide explanations for the induced parity and time-reversal violations consequently implied in a quantum framework. |
