Five-dimensional black holes in heterotic string theory
Abstract
We review recent results on near-horizon static black hole solutions and entropy in R2-corrected N=2 SUGRA in D=5, focusing on actions connected to heterotic string compactified on K3× S1. Comparison with α'-perturbative results, results obtained by using simple Gauss-Bonnet R2-correction, OSV conjecture and microscopic stringy description (for small black holes) shows that situation in D=5 is, in a sense, even more interesting then in D=4.
