Rotating Dyonic Black Holes in Heterotic String Theory

TL;DR

This paper investigates a specific class of rotating dyonic black holes in heterotic string theory, revealing their unique charge configurations and unbounded gyromagnetic ratios, contributing to understanding black hole properties in string theory.

Contribution

It introduces a new class of rotating dyonic black holes with distinct charge arrangements and analyzes their gyromagnetic ratios, which are generally unbounded.

Findings

Gyromagnetic ratios are unbounded.

Black holes have independent electric charges in left and right sectors.

Electric and magnetic vectors are orthogonal in both sectors.

Abstract

We study a class of rotating dyonic black holes in the heterotic string theory in four dimension which have left, right independent electric charges but have same magnitude for the left and right magnetic charges. In both left and right sector the electric and the magnetic vectors are orthogonal to each other. The gyromagnetic(electric) ratios are in general found not to have an upper bound.
