CCNV Space-Times as Potential Supergravity Solutions

Abstract EN

It is of interest to study supergravity solutions preserving a nonminimal fraction of supersymmetries.

A necessary condition for supersymmetry to be preserved is that the space-time admits a Killing spinor and hence a null or time-like Killing vector field.

Any space-time admitting a covariantly constant null vector (CCNV) field belongs to the Kundt class of metrics and more importantly admits a null Killing vector field.

We investigate the existence of additional non-space-like isometries in the class of higher-dimensional CCNV Kundt metrics in order to produce potential solutions that preserve some supersymmetries.
