On the Moduli Space of non-BPS Attractors for N = 2 Symmetric Manifolds

چکیده
We study the “flat” directions of non-BPS extremal black hole attractors for N = 2, d = 4 supergravities whose vector multiplets’ scalar manifold is endowed with homogeneous symmetric special Kähler geometry. The non-BPS attractors with non-vanishing central charge have a moduli space described by real special geometry (and thus related to the d = 5 parent theory), whereas the moduli spaces of non-BPS attractors with vanishing central charge are certain Kähler homogeneous symmetric manifolds. The moduli spaces of the non-BPS attractors of the corresponding N = 2, d = 5 theories are also indicated, and shown to be rank-1 homogeneous symmetric manifolds.

SAM Lectures on Extremal Black Holes in d = 4 Extended Supergravity
We report on recent results in the study of extremal black hole attractors in N = 2, d = 4 ungauged Maxwell-Einstein supergravities. For homogeneous symmetric scalar manifolds, the three general classes of attractor solutions with non-vanishing Bekenstein-Hawking entropy are discussed. They correspond to three (inequivalent) classes of orbits of the charge vector, which sits in the relevant sym...
متن کاملAttractors in Black
We review recent results in the study of attractor horizon geometries (with nonvanishing Bekenstein-Hawking entropy) of dyonic extremal d = 4 black holes in supergravity. We focus on N = 2, d = 4 ungauged supergravity coupled to a number nV of Abelian vector multiplets, outlining the fundamentals of the special Kähler geometry of the vector multiplets’ scalar manifold (of complex dimension nV )...
متن کاملOrbits and Attractors for N = 2 Maxwell-einstein Supergravity Theories in Five Dimensions
BPS and non-BPS orbits for extremal black-holes in N = 2 MaxwellEinstein supergravity theories (MESGT) in five dimensions were classified long ago by the present authors for the case of symmetric scalar manifolds. Motivated by these results and some recent work on non-supersymmetric attractors we show that attractor equations in N=2 MESGTs in d = 5 do indeed possess the distinct families of sol...
متن کاملBPS and non BPS 7 D Black Attractors in M - Theory on K 3 El Hassan Saidi
We study the BPS and non BPS black attractors in 7D N = 2 supergravity embedded in 11D M-theory compactified on K3. Combining Kahler and complex moduli in terms of SO (3) representations, we build the Dalbeault like (DL) basis for the second cohomology of K3 and set up the fundamental relations of the special ”hyperKahler” geometry of the underlying moduli space of the 7D theory. We study the a...
