关于$T\bar{T}$形变和超对称性

On $T\bar{T}$ deformations and supersymmetry

Marco Baggio, Alessandro Sfondrini, Gabriele Tartaglino-Mazzucchelli, Harriet Walsh

摘要:

研究了二维超对称量子场论的"$T\bar{T}$"形变。更准确地说,我们表明,通过使用的超导多重态的守恒方程,$T\bar{T}$变形算子可以构造为一个超对称的后代。在这里,我们专注于$\mathcal{N}=(1,0)$和$\mathcal{N}=(1,1)$超对称性。作为例子,我们详细分析了自由$\mathcal{N}=(1,0)$超对称作用量的$T\bar{T}$形变。我们还认为,$T\bar{T}$和弦理论之间的联系可以扩展到超弦:通过分析超弦在平坦空间中的光锥规范固定,我们显示了弦作用量与鼻子上八个$\mathcal{N}=(1,1)$标量多重态的自由理论的$T\bar{T}$变形的对应关系。我们评论如何这些建设涉及到$T\bar{T}$变形的几何解释,最近在文献中讨论。

英文摘要:

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