Seven-branes and Supersymmetry
Eric A. Bergshoeff, Jelle Hartong, Tomas Ortin +1
We re-investigate the construction of half-supersymmetric 7-brane solutions of IIB supergravity. Our method is based on the requirement of having globally well-defined Killing spin…
Supersymmetry and cosmic censorship
T. Ortin
We show that requiring unbroken supersymmetry everywhere in black-hole-type solutions of N=2,d=4 supergravity coupled to vector supermultiplets ensures in most cases absence of nak…
SL(2,R)-invariant IIB Brane Actions
Eric A. Bergshoeff, Mees de Roo, Sven F. Kerstan +2
We give a universal SL(2,R)-invariant expression for all IIB p-brane actions with p=-1,1,3,5,7,9. The Wess-Zumino terms in the brane actions are determined by requiring (i) target…
Supersymmetric solutions of N=2 d=4 sugra: the whole ungauged shebang
Mechthild Huebscher, Patrick Meessen, Tomas Ortin
In this article we complete the classification of the supersymmetric solutions of N=2 D=4 ungauged supergravity coupled to an arbitrary number of vector- and hypermultiplets. We fi…
Supersymmetry, attractors and cosmic censorship
Jorge Bellorin, Patrick Meessen, Tomas Ortin
We show that requiring unbroken supersymmetry everywhere in black-hole-type solutions of N=2,d=4 supergravity coupled to vector supermultiplets ensures in most cases absence of nak…
IIA Ten-forms and the Gauge Algebras of Maximal Supergravity Theories
Eric A. Bergshoeff, Mees de Roo, Sven F. Kerstan +2
We show that IIA supergravity can be extended with two independent 10-form potentials. These give rise to a single BPS IIA 9-brane. We investigate the bosonic gauge algebra of both…
