十六超对称理论中的高阶导数耦合

On Higher Derivative Couplings in Theories with Sixteen Supersymmetries

Ying-Hsuan Lin, Shu-Heng Shao, Yifan Wang, Xi Yin

摘要:

通过对膜体超振幅的考虑,我们给出了关于规范理论与超引力的高阶导数耦合的新的非重整化定理的简单论证,其中包含16种超对称性。这导致了IIB型弦论中D3-膜有效耦合的一些精确结果。我们还得到了高维算子在六维(0,2)超共形理论的环面紧化中的精确结果。

英文摘要:

We give simple arguments for new non-renormalization theorems on higher derivative couplings of gauge theories to supergravity, with sixteen supersymmetries, by considerations of brane-bulk superamplitudes. This leads to some exact results on the effective coupling of D3-branes in type IIB string theory. We also derive exact results on higher dimensional operators in the torus compactification of the six dimensional (0, 2) superconformal theory.
