Kaluza-Klein magnetic monopole a la Taub-NUT
Abstract
In this paper, we consider a new vacuum solution of the Kaluza-Klien theory which resembles the Taub-NUT metric in five dimensions and we investigate its physical properties as projected into four dimensions. We show that the Taub-NUT Kaluza-Klein vacuum solution in five dimensions is a static magnetic monopole in four dimensions. We find that the four dimensional matter properties do not obey the equation of state of radiation and there is no event horizon.
