Multi-black holes and instantons in effective string theory

General Relativity and Quantum Cosmology 2015-06-25 v1

Abstract

The effective action for string theory which takes into account non-minimal coupling of moduli admits multi-black hole solutions. The euclidean continuation of these solutions can be interpreted as an instanton mediating the splitting and recombination of the throat of extremal magnetically charged black holes.
