“…Gauged N = 4 supergravity obtained from Scherk-Schwarz compactifications [11] has been considered in the past [12,13,14], and also more recently in combination with flux compactification [15]- [20]. Nevertheless, to our knowledge the SU(1, 1) duality angles [21], which play an essential role in obtaining extrema with a positive cosmological constant, have not been given a higher-dimensional origin.…”

Mario TrigianteSpinoza Institute Leuvenlaan 4, 3508 TD Utrecht, The Netherlands E-mail: m.trigiante@phys.uu.nl Abstract: We discuss the potential and mass-matrix of gauged N = 4 matter coupled supergravity for the case of six matter multiplets, extending previous work by considering the dependence on all scalars. We consider all semi-simple gauge groups and analyse the potential and its first and second derivatives in the origin of the scalar manifold. Although we find in a number of cases an extremum with a positive cosmological constant, these are not stable under fluctuations of all scalar fields.

“…Consider for example 4D, N = 4 supergravity coupled to n Abelian vector multiplets [4]. This theory contains (6 + n) vector fields, where 6 come from the supergravity multiplet (i.e., there are six 'graviphotons') and the remaining n are supplemented by the n vector multiplets.…”

Unified N = 2 Maxwell-Einstein supergravity theories (MESGTs) are supergravity theories in which all the vector fields, including the graviphoton, transform in an irreducible representation of a simple global symmetry group of the Lagrangian. As was established long time ago, in five dimensions there exist only four unified Maxwell-Einstein supergravity theories whose target manifolds are symmetric spaces. These theories are defined by the four simple Euclidean Jordan algebras of degree three. In this paper, we show that, in addition to these four unified MESGTs with symmetric target spaces, there exist three infinite families of unified MESGTs as well as another exceptional one. These novel unified MESGTs are defined by non-compact (Minkowskian) Jordan algebras, and their target spaces are in general neither symmetric nor homogeneous. The members of one of these three infinite families can be gauged in such a way as to obtain an infinite family of unified N = 2 Yang-MillsEinstein supergravity theories, in which all vector fields transform in the adjoint representation of a simple gauge group of the type SU (N, 1). The corresponding gaugings in the other two infinite families lead to Yang-Mills-Einstein supergravity theories coupled to tensor multiplets.

We review work done over the last years on the macroscopic and microscopic entropy of supersymmetric black holes in fourdimensional N = 2 supergravity and in N = 2 compactifications of string theory and M-theory. Particular emphasis is put on the crucial role of higher curvature terms and of modifications of the area law in obtaining agreement between the macroscopic entropy, which is a geometric property of black hole solutions and the microscopic entropy, which is computed by state counting in Calabi-Yau compactifications of string or M-theory. We also discuss invariance properties of the entropy under stringy T-duality and S-duality transformations in N = 2, 4 compactifications in presence of higher curvature terms.In order to make the paper self-contained we review the laws of black hole mechanics in higher derivative gravity, the definition of entropy as a surface charge, the superconformal offshell description of N = 2 supergravity, special geometry, and N = 2 compactifications of heterotic and type II string theory and of M-theory.
