Beyond the near-horizon limit: stringy corrections to heterotic black holes

We study the rst-order in α¹ corrections to 4-charge black holes (with the Reissner-Nordstr om black hole as a particular example) beyond the near-horizon limit in the Heterotic Superstring effective action framework. The higher-curvature terms behave as delocalized sources in the equations of motio...
