摘要:

利用Gaberdiel和Gopakumar最近描述的自由场世界片实现,构造了高自旋超代数$hs(2,2|4)$的非平凡最低生成元.它们由双线性的ambitwistor-like字段之间的立方项。我们还获得了世界表描述的Sezgin和Sundell二十年前的研究结果所熟悉的振荡器的建设。明确地确定了李超代数$PSU(2,2|4)$的共形权- $1$生成元与$hs(2,2|4)$的上述共形权- $3$生成元之间的算子乘积展开式(OPEs)的一阶极点,并在世界片理论中给出了附加生成元.

英文摘要:

By using the free field worldsheet realization described by Gaberdiel and Gopakumar recently, we construct the nontrivial lowest generators of the higher spin superalgebra $hs(2,2|4)$. They consist of cubic terms between the bilinears of ambitwistor-like fields. We also obtain the worldsheet description for the findings of Sezgin and Sundell twenty years ago given by the familiar oscillator construction. The first order poles of the operator product expansions (OPEs), between the conformal weight-$1$ generators of Lie superalgebra $PSU(2,2|4)$ and the above conformal weight-$3$ generators of $hs(2,2|4)$, are determined explicitly and the additional generators appear in the worldsheet theory.
