Supersymmetric space-time symmetry breaking sources

We construct new families of deformed supersymmetric field theories which break space-time symmetries but preserve half of the original supersymmetry. We do this by writing deformations as couplings to background multiplets. In many cases it is important to use the off-shell representation as auxiliary fields of the non-dynamical fields must be turned on to preserve supersymmetry. We also consider backgrounds which preserve some superconformal symmetry, finding scale-invariant field profiles, as well as N $$ \mathcal{N} $$ = 2 theories on S 3 . We discuss how this is related to previous work on interface SCFTs and other holographic calculations.
