We investigate the “TT ̄” deformations of two-dimensional supersymmetric quantum field theories. More precisely, we show that, by using the conservation equations for the supercurrent multiplet, the TT ̄ deforming operator can be constructed as a super- symmetric descendant. Here we focus on N = (1, 0) and N = (1, 1) supersymmetry. As an example, we analyse in detail the TT ̄ deformation of a free N = (1, 0) supersymmetric action. We also argue that the link between TT ̄ and string theory can be extended to su- perstrings: by analysing the light-cone gauge fixing for superstrings in flat space, we show the correspondence of the string action to the TT ̄ deformation of a free theory of eight N = (1, 1) scalar multiplets on the nose. We comment on how these constructions relate to the geometrical interpretations of TT ̄ deformations that have recently been discussed in the literature.
