Scalar masses in general N=2 gauged supergravity theories
Francesca Catino, Claudio A. Scrucca, Paul Smyth
We readdress the question of whether any universal upper bound exists on the square mass m^2 of the lightest scalar around a supersymmetry breaking vacuum in generic N=2 gauged sup…
The rigid limit of N=2 supergravity
Bobby E. Gunara, Jan Louis, Paul Smyth +2
In this paper we review the rigid limit of N=2 supergravity coupled to vector and hypermultiplets. In particular we show how the respective scalar field spaces reduce to their glob…
Simple metastable de Sitter vacua in N=2 gauged supergravity
Francesca Catino, Claudio A. Scrucca, Paul Smyth
We construct a simple class of N=2 gauged supergravity theories that admit metastable de Sitter vacua, generalizing the recent work done in the context of rigid supersymmetry. The…
Electrically gauged N=4 supergravities in D=4 with N=2 vacua
Christoph Horst, Jan Louis, Paul Smyth
We study N=2 vacua in spontaneously broken N=4 electrically gauged supergravities in four space-time dimensions. We argue that the classification of all such solutions amounts to s…
Metastable spontaneous breaking of N=2 supersymmetry
Benoit Legeret, Claudio A. Scrucca, Paul Smyth
We show that contrary to the common lore it is possible to spontaneously break N=2 supersymmetry even in simple theories without constant Fayet-Iliopoulos terms. We consider the mo…
Metastable de Sitter vacua in N=2 to N=1 truncated supergravity
Francesca Catino, Claudio A. Scrucca, Paul Smyth
We study the possibility of achieving metastable de Sitter vacua in general N=2 to N=1 truncated supergravities without vector multiplets, and compare with the situations arising i…
Supersymmetric Vacua in N=2 Supergravity
Jan Louis, Paul Smyth, Hagen Triendl
We use the embedding tensor formalism to analyse maximally symmetric backgrounds of N=2 gauged supergravities which have the full N=2 supersymmetry. We state the condition for N=2…
The N=1 Low-Energy Effective Action of Spontaneously Broken N=2 Supergravities
Jan Louis, Paul Smyth, Hagen Triendl
We consider the class of four-dimensional N=2 gauged supergravities whose maximally symmetric ground states leave only one of the two supersymmetries intact. For these theories we…
Spontaneous N=2 to N=1 Supersymmetry Breaking in Supergravity and Type II String Theory
Jan Louis, Paul Smyth, Hagen Triendl
Using the embedding tensor formalism we give the general conditions for the existence of N=1 vacua in spontaneously broken N=2 supergravities. Our results confirm the necessity of…
Domain wall flow equations and SU(3)xSU(3) structure compactifications
Paul Smyth, Silvia Vaulà
We study supersymmetric domain wall solutions in four dimensions arising from the compactification of type II supergravity on a SU(3)xSU(3) structure manifold. Using a pure spinor…
Black holes, first-order flow equations and geodesics on symmetric spaces
Jan Perz, Paul Smyth, Thomas Van Riet +1
For both extremal and non-extremal spherically symmetric black holes in theories with massless scalars and vectors coupled to gravity, we derive a general form of first-order gradi…
First-order flow equations for extremal and non-extremal black holes
Jan Perz, Paul Smyth, Thomas Van Riet +1
We derive a general form of first-order flow equations for extremal and non-extremal, static, spherically symmetric black holes in theories with massless scalars and vectors couple…
A first-order formalism for timelike and spacelike brane solutions
Bert Janssen, Paul Smyth, Thomas Van Riet +1
We show that the construction of BPS-type equations for non-extremal black holes due to Miller et. al. can be extended to branes of arbitrary dimension and, more importantly, to ti…
Kaluza-Klein Induced Supersymmetry Breaking for Braneworlds in Type IIB Supergravity
Jean-Luc Lehners, Paul Smyth, K. S. Stelle
We consider Z_2-symmetric braneworlds arising from 5-sphere compactifications with 5-form flux in type IIB supergravity. This Kaluza-Klein reduction produces a D=5 theory which sup…
The energy and stability of D-term strings
Andrés Collinucci, Paul Smyth, Antoine Van Proeyen
Cosmic strings derived from string theory, supergravity or any theory of choice should be stable if we hope to observe them. In this paper we consider D-term strings in D=4, N=1 su…
Supersymmetric D-branes and calibrations on general N=1 backgrounds
Luca Martucci, Paul Smyth
We study the conditions to have supersymmetric D-branes on general {\cal N}=1 backgrounds with Ramond-Ramond fluxes. These conditions can be written in terms of the two pure spinor…
