4d F(4) gauged supergravity and black holes of class ?

A bstract We perform a consistent reduction of 6d matter-coupled F(4) supergravity on compact Riemann surface $$ {\Sigma}_{\mathfrak{g}} ? g genus \mathfrak{g} , at the level bosonic action. The result is an \mathcal{N} N = 2 gauged coupled to two vector multiplets and single hypermultiplet. four-dimensional model holographically dual 3d superconformal field theories class ?, describing different brane systems in massive type IIA IIB wrapped . naive leads non-standard 4d mixed duality frame with both electric magnetic gauge fields, as well tensor, that can be only described embedding tensor formalism. Upon chain electromagnetic dualities, we are able determine scalar manifolds gaugings uniquely specify standard frame. then use construct first examples static dyonic black holes AdS 6 microscopic counting their entropy via 5d topologically twisted index. Finally, show existence further subtruncations massless sector theory, such Fayet-Iliopoulos T 3 minimal supergravity. turn find new asymptotically 4 solutions, providing predictions for squashed S partition functions refined indices ? theories.
