MULTIDIMENSIONAL GEOMETRICAL MODEL OF THE RENORMALIZED ELECTRICAL CHARGE WITH SPLITTING OFF THE EXTRA COORDINATES

A geometrical model of electric charge is proposed. This model has "naked" charge screened with a "fur-coat" consisting of virtual wormholes. The 5-D wormhole solution in the Kaluza–Klein theory is the "naked" charge. The splitting off of the 5-D happens on the two spheres (null surfaces) bonding this 5-D wormhole. This allows one to sew two Reissner–Nordström black holes onto it on both sides. The virtual wormholes entrap a part of the electrical flux lines coming into the "naked" charge. This effect essentially changes the charge visible at infinity so that it satisfies the real relation m2<e2.

Abstract Kaluza–Klein theory is a popular alternative theory of gravity, with both non-rotating and rotating black hole solutions known. This allows for the possibility that the theory could be observationally tested. We present a model which calculates the reflection spectrum of a black hole accretion disk system, where the black hole is described by a rotating solution of the Kaluza–Klein theory. We also use this model to analyze X-ray data from the stella-mass black hole in GRS 1915+105 and provide constraints on the free parameters of the Kaluza–Klein black holes.

We generalize the results of arXiv:1212.1875 and arXiv:1212.6919 on attraction basins and their boundaries to the case of a specific class of rotating black holes, namely the ergo-free branch of extremal black holes in Kaluza–Klein theory. We find that exact solutions that span the attraction basin can be found even in the rotating case by appealing to certain symmetries of the equations of motion. They are characterized by two asymptotic parameters that generalize those of the non-rotating case, and the boundaries of the basin are spinning versions of the (generalized) subtractor geometry. We also give examples to illustrate that the shape of the attraction basin can drastically change depending on the theory.
