Abstract

We describe a non-minimal higher-derivative extension of Einstein-Maxwell\ntheory in which electrically-charged black holes and point charges have\nglobally regular gravitational and electromagnetic fields. We provide an exact\nstatic spherically symmetric solution of this theory that reduces to the\nReissner-Nordstr "om one at weak coupling, but in which the singularity at\nr=0 is regularized for arbitrary mass and (non-vanishing) charge. We discuss\nthe properties of these solutions and comment on the physical significance of\nour results.\n
