چکیده
We analyze the gauging of Abelian isometries on the hypermultiplet scalar manifolds of N = 2 supergravity in four dimensions. This involves a study of symmetric special quaternionic-Kähler manifolds, building on the work of de Wit and Van Proeyen. In particular we compute the general set of Killing prepotentials and associated compensators for these manifolds. This allows us to glean new insights about AdS4 vacua which preserve the full N = 2 supersymmetry as well as BPS static black hole horizons.

Gaugings at angles from orientifold reductions
We consider orientifold reductions to N = 4 gauged supergravity in four dimensions. A special feature of this theory is that different factors of the gauge group can have relative angles with respect to the electro-magnetic SL(2) symmetry. These are crucial for moduli stabilisation and De Sitter vacua. We show how such gaugings at angles generically arise in orientifold reductions.
متن کاملOff-shell dimensional reduction of 5D orbifold supergravity
We present a systematic way for deriving a four-dimensional (4D) effective action of the fivedimensional (5D) orbifold supergravity respecting the N = 1 off-shell structure. As an illustrating example, we derive a 4D effective theory of the 5D gauged supergravity with a universal hypermultiplet and generic gaugings, which includes the 5D heterotic M-theory and the supersymmetric Randall-Sundrum...
متن کاملNoncompact Gaugings , Chiral Reduction and Dual Sigma Models in Supergravity
We show that the half-maximal SU (2) gauged supergravity with topological mass term admits coupling of an arbitrary number of n vector multiplets. The chiral circle reduction of the ungauged theory in the dual 2-form formulation gives N = (1, 0) supergravity in 6D coupled to 3p scalars that parametrize the coset SO(p, 3)/SO(p) × SO(3), a dilaton and (p + 3) axions with p ≤ n. Demanding that R-s...
متن کاملNon-Abelian BPS Monopoles in N=4 Gauged Supergravity
We study static, spherically symmetric, and purely magnetic solutions of SU(2) × SU(2) gauge supergravity in four dimensions. A systematic analysis of the supersymmetry conditions reveals solutions which preserve 1/8 of the supersymmetries and are characterized by a BPS-monopole-type gauge field and a globally hyperbolic, everywhere regular geometry. These present the first known example of non...
متن کامل0 Gauging the Full R - Symmetry Group in Five - dimensional , N = 2 Yang - Mills / Einstein / tensor Supergravity 1
We show that certain 5d, N = 2 Yang-Mills/Einstein supergravity theories admit the gauging of the full R-symmetry group, SU(2)R, of the underlying N = 2 Poincaré superalgebra. This generalizes the previously studied Abelian gaugings of U(1)R ⊂ SU(2)R, and completes the construction of the most general vector and tensor field coupled 5d, N = 2 supergravity theories with gauge interactions. The g...
