On gravity self-completeness in higher dimensions — •Sven Köppel^1,2, Euro Spalluci^3,4, Piero Nicolini^1,2 und Marcus Bleicher^1,2 — ¹Institut für theoretische Physik, Goethe-Universität Frankfurt am Main, Deutschland — ²Frankfurt Institute for Advanced Sciences, Frankfurt am Main, Deutschland — ³Dipartimento di Fisica, Sezione di Fisica Teorica, Università degli Studi di Trieste, Italy — ⁴INFN, Sezione di Trieste, Strada Costiera 11, Trieste, Italy

There is a great expectation about the possibility for gravity of being self-complete, i.e., able to prevent the access to scales smaller of the Planck scale. According to such a paradigm, we propose black hole geometries with an improved short scale behavior. Specifically such models have a regular center and a stable cold evaporation end-point (remnant). We show that the proposed geometries can be derived by a non-local deformation of the Einstein-Hilbert action and are compatible with the large spatial extradimension scenario.
