20.500.12556/DKUM-81528 Conformal symmetries for extremal black holes with general asymptotic scalars in STU supergravity We present a construction of the most general BPS black holes of STU supergravity (N = 2 supersymmetric D = 4 supergravity coupled to three vector supermultiplets) with arbitrary asymptotic values of the scalar fields. These solutions are obtained by acting with a subset of the global symmetry generators on STU BPS black holes with zero values of the asymptotic scalars, both in the U-duality and the heterotic frame. The solutions are parameterized by fourteen parameters: four electric and four magnetic charges, and the asymptotic values of the six scalar fields. We also present BPS black hole solutions of a consistently truncated STU supergravity, which are parameterized by two electric and two magnetic charges and two scalar fields. These latter solutions are significantly simplified, and are very suitable for further explicit studies. We also explore a conformal inversion symmetry of the Couch-Torrence type, which maps any member of the fourteen-parameter family of BPS black holes to another member of the family. Furthermore, these solutions are expected to be valuable in the studies of various swampland conjectures in the moduli space of string compactifications. black holes extended supersymmetry supergravity models string theory črne luknje razširjena supersimetrija supergravitacija teorija strun astrofizika true false true SISSA Angleški jezik Slovenski jezik Znanstveno delo 2022-04-08 14:56:48 2023-10-16 09:51:54 2024-08-09 13:33:47 0000-00-00 00:00:00 2021 0 0 Str. 1-44 Št. 9, št. članka 188 6. okt. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-07-12 2021-09-09 2021-09-28 52 97932547 10.1007/JHEP09(2021)188 1029-8479 Conformal_symmetries_for_extremal_black_holes_Cvetic_2021.pdf Conformal_symmetries_for_extremal_black_holes_Cvetic_2021.pdf 1 EFB275560FA641159E169507A2D8FA96 b51c7bce3e6b67ed3b97ed02bf5eaa2efae2015b9b9ea9673af90871c5ab41f5 78380a1a-69d1-11ee-b6cb-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173566 https://link.springer.com/article/10.1007/JHEP09(2021)188 0 5a3ed4a4-b73b-11ec-b648-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=157244 Univerza v Mariboru 0 0 0
