Title: | Characterizing black hole metrics in quadratic gravity | Authors: | BONANNO, Alfio Maurizio Silveravalle, S. |
Issue Date: | 2019 | Journal: | PHYSICAL REVIEW D | Number: | 99 | Issue: | 10 | First Page: | 101501 | Abstract: | The recent discovery of non-Schwarzschild black hole spacetimes has opened new directions of research in higher-derivative gravitational theories. However, despite intense analytical and numerical efforts, the link with the linearized theory is still poorly understood. In this work we address this point for the Einstein-Weyl Lagrangian, whose weak field limit is characterized by the standard massless graviton and a spin-2 ghost. We show that the strength of the Yukawa term at infinity determines the thermal properties of the black hole and the structure of the singularity near r =0 . Moreover, inspired by recent results in the asymptotic safety scenario we investigate the consequences of an imaginary ghost mass. In this case we find a countable set of solutions all characterized by spatial oscillations of typical wavelength determined by the mass of the spin-2 field. | URI: | http://hdl.handle.net/20.500.12386/30433 | URL: | https://journals.aps.org/prd/abstract/10.1103/PhysRevD.99.101501 | ISSN: | 2470-0010 | DOI: | 10.1103/PhysRevD.99.101501 | Bibcode ADS: | 2019PhRvD..99j1501B | Fulltext: | open |
