On T T ¯ $$ T\overline{T} $$ deformations and supersymmetry
Journal of High Energy Physics(2019)
摘要
We investigate the “
$$ T\overline{T} $$
” deformations of two-dimensional supersymmetric quantum field theories. More precisely, we show that, by using the conservation equations for the supercurrent multiplet, the
$$ T\overline{T} $$
deforming operator can be constructed as a super-symmetric descendant. Here we focus on
$$ \mathcal{N} = \left(1,0\right) $$
and
$$ \mathcal{N} = \left(1,1\right) $$
supersymmetry. As an example, we analyse in detail the
$$ T\overline{T} $$
deformation of a free
$$ \mathcal{N} = \left(1,0\right) $$
supersymmetric action. We also argue that the link between
$$ T\overline{T} $$
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
$$ T\overline{T} $$
deformation of a free theory of eight
$$ \mathcal{N} = \left(1,1\right) $$
scalar multiplets on the nose. We comment on how these constructions relate to the geometrical interpretations of
$$ T\overline{T} $$
deformations that have recently been discussed in the literature.
