D=4, N=2 Supergravity in the Presence of Vector-Tensor Multiplets and the Role of higher p-forms in the Framework of Free Differential Algebras
Laura Andrianopoli, Riccardo D'Auria, Luca Sommovigo
We thoroughly analyze at the bosonic level, in the framework of Free Differential Algebras (FDA), the role of 2-form potentials setting in particular evidence the precise geometric…
Non-BPS Attractors in 5d and 6d Extended Supergravity
L. Andrianopoli, S. Ferrara, A. Marrani +1
We connect the attractor equations of a certain class of N=2, d=5 supergravities with their (1,0), d=6 counterparts, by relating the moduli space of non-BPS d=5 black hole/black st…
First Order Description of Black Holes in Moduli Space
Laura Andrianopoli, Riccardo D'Auria, Emanuele Orazi +1
We show that the second order field equations characterizing extremal solutions for spherically symmetric, stationary black holes are in fact implied by a system of first order equ…
Black-Hole Attractors in N=1 Supergravity
Laura Andrianopoli, Riccardo D'Auria, Sergio Ferrara +1
We study the attractor mechanism for N=1 supergravity coupled to vector and chiral multiplets and compute the attractor equations of these theories. These equations may have soluti…
On the coupling of tensors to gauge fields: D=5, N=2 supergravity revisited
Laura Andrianopoli, Riccardo D'Auria, Luca Sommovigo
A general free differential algebra encoding the anti-Higgs mechanism among two-index antisymmetric tensors and gauge vectors is analyzed at the full group theoretical level. N=2 s…
Extremal Black Holes in Supergravity
Laura Andrianopoli, Riccardo D'Auria, Sergio Ferrara +1
We present the main features of the physics of extremal black holes embedded in supersymmetric theories of gravitation, with a detailed analysis of the attractor mechanism for BPS…
