KALUZA-KLEIN BLACK HOLES WITHIN HETEROTIC STRING THEORY ON A TORUS

TL;DR

This paper explores how certain 4D black hole solutions from Kaluza-Klein theory naturally emerge within heterotic string theory compactified on a 6-torus, after specific field truncations.

Contribution

It demonstrates that 4D black holes from Kaluza-Klein theory are a subset of solutions in heterotic string theory on a 6-torus, clarifying their relationship.

Findings

Kaluza-Klein black holes are embedded in heterotic string theory.

Consistent truncation relates gauge and tensor fields to black hole solutions.

Provides a framework for understanding black holes in string theory context.

Abstract

We point out that in heterotic string theory compactified on a 6-torus, after a consistent truncation of the 10-d gauge fields and the antisymmetric tensor fields, 4-dimensional black holes of Kaluza-Klein theory on a 6-torus constitute a subset of solutions.
