闭弦3-圈振幅与S-对偶

The closed-string 3-loop amplitude and S-duality

Humberto Gomez, Carlos R. Mafra

摘要:

在IIA型和IIB型超弦理论中,我们用纯旋量形式计算了四点三圈振幅的低能极限(包括其总系数)。计算结果与Green和Vanhove基于S-对偶性对IIB型$D^6 R^4$相互作用系数的预测一致。

英文摘要:

The low-energy limit of the four-point 3-loop amplitude (including its overall coefficient) is computed in both type IIA and IIB superstring theories using the pure spinor formalism. The result is shown to agree with the prediction of the coefficient for the type IIB $D^6 R^4$ interaction made by Green and Vanhove based on S-duality considerations.
