Cosmic Censorship Violation for a Class of Supersymmetric Solitons

الأصل · EN

We study vacuum domain walls in a class of four-dimensional N=1 supergravity theories where along with the matter field, forming the wall, there is more than one ``dilaton'', each respecting SU(1,1) symmetry in their sub-sector. We find supersymmetric (planar, static) walls, interpolaing between Minkowski vacuum and a new class of supersymmetric vacua which have a naked (planar) singularity. Such walls provide the first example of supersymmetric classical ``solitons'' with naked singularities, and thus violate the (strong) cosmic censorship conjecture within a supersymmetric theory.
