Space-filling branes & gaugings

Understand

We consider in any dimension the supersymmetric $\mathbb{Z}_2$ truncations of the maximal supergravity theories.

• In each dimension and for each truncation we determine all the sets of 1/2-BPS space-filling branes that preserve the supersymmetry of the truncated theory and the representations of the symmetry of such theory to which they belong.
• We show that in any dimension below eight these sets always contain exotic branes, that are objects that do not have a ten-dimensional origin.
• We repeat the same analysis for half-maximal theories and for the quarter-maximal theories in four and three dimensions.
