deformations with supersymmetry

arXiv:1904.04760 · doi:10.1103/PhysRevD.100.046017

Abstract

We investigate the behaviour of two-dimensional quantum field theories with supersymmetry under a deformation induced by the `' composite operator. We show that the deforming operator can be defined by a point-splitting regularisation in such a way as to preserve supersymmetry. As an example of this construction, we work out the deformation of a free theory and compare to that induced by the Noether stress-energy tensor. Finally, we show that the supersymmetric deformed action actually possesses symmetry, half of which is non-linearly realised.
