利用超流中的双线性无关算子，构造了具有（2，2）超对称性的二维理论的可解变形。这个超流平方算子是明显超对称的，并且在使用守恒律后等价于杆上的T（T）。作为说明性的例子，我们变形理论涉及一个单一的（2，2）手征超场。我们证明了变形自由理论与（2，2）Nambu-Goto作用量是在壳等价的。在经典水平上，具有超势的模型表现出更令人惊讶的行为：变形理论在物理势中表现出改变真空结构的极点。这表明T（T）在棒型上的不相关变形也可能影响红外物理。
We construct a solvable deformation of two-dimensional theories with (2, 2) supersymmetry using an irrelevant operator which is a bilinear in the supercurrents. This supercurrent-squared operator is manifestly supersymmetric and equivalent to T (T) over bar after using conservation laws. As illustrative examples, we deform theories involving a single (2, 2) chiral superfield. We show that the deformed free theory is on-shell equivalent to the (2, 2) Nambu-Goto action. At the classical level, models with a superpotential exhibit more surprising behavior: the deformed theory exhibits poles in the physical potential which modify the vacuum structure. This suggests that irrelevant deformations of T (T) over bar type might also affect infrared physics.
