Super throats with non trivial scalars

Abstract

We find new BPS solutions in N = 2 D = 4 Fayet-Iliopoulos gauged supergravity with STU prepotential. These are stationary solutions carrying a Kerr-Newman throat spacetime geometry and are everywhere regular. One of the three scalar vector fields is non constant. Moreover, they carry non vanishing magnetic fluxes and dipolar electric fields.

“…This is indeed what happens for the static version of the solutions in [5] (see [4]), which interpolate between a AdS 2 × Σ 1 2 -supersymmetric geometry on the horizon, and a full supersymmetric AdS 4 . But things go very different for the new solutions in [19], where g 0 , g 1 < 0 and g 2 , g 3 > 0. In that case…”

“…However, while the same symmetry holds for the gauge fields (up to a sign), it does not extend to the scalar fields, which assume different values at the horizons. As a consequence, even though the geometry is the same, only at one of the horizon the full supersymmetric solution of [19] is reproduced: the second horizon results to be non supersymmetric. It is worth to mention that the values of the scalar fields at the horizons depend on a real free modulus.…”

“…leading then to a de Sitter space! To look for the explicit solution having as near horizon limit the static solution in [19], we make the ansatz…”

“…In recent years there have been progresses in finding BPS, non BPS and thermal black holes solutions in N = 2 gauged supergravity in four dimensions, coupled with matter, see for example [20][21][22][23][24][25][26][27][28] and [29]. The work presented here belongs in this precise context, and is inspired by [19], where a new class of near horizon solutions, both stationary and static, in gauged supergravity coupled to scalar fields have been found, but they resisted to any effort in determining the black hole solutions of which they are the near horizon limit. In this work we fill this gap for the static case, and will show that a number of surprises arise.…”
