Some properties of a $\Delta-$string

TL;DR

This paper explores 5D gravitational flux tubes, called Δ-strings, showing they can act as string-like objects with electric charges at attachment points, while magnetic charges are excluded.

Contribution

It introduces a model for attaching Δ-strings to spacetime and demonstrates their charge properties, providing insights into higher-dimensional string-like objects.

Findings

Δ-strings can be modeled as 5D flux tubes with Planck-scale cross section.

Attachment points of Δ-strings behave as electric charges.

Magnetic charges are not supported in this model.

Abstract

The properties of 5D gravitational flux tubes are considered. With the cross section and 5th dimension in the Planck region such tubes can be considered as string-like objects, namely $\Delta-$strings. A model of attachment of $\Delta-$string to a spacetime is offered. It is shown that the attachment point is a model of an electric charge for an observer living in the spacetime. Magnetic charges are forbidden in this model.
