N = 8超引力的负引力

Notophs of N = 8 supergravity

Igor Bandos, Tomas Ortın

摘要:

本文研究了超空间中N=8 D=4的非规范超引力张量规范场。这些由G=E(7(+7))的伴随表示中的2-形式势描述。超空间约束的自然候选者对它们的场强的一致性固定了广义比安奇恒等式的形式,并且还要求具有G/H=E(7(+7))/SU(8)生成元的指数的势与N=8,D=4的超引力多重态的标量对偶。相反,对应于SU(8)生成元的2型势的场强与费米子双线性是对偶的,因此这些势是辅助场而不是物理场。然而,它们的存在对于建立一个N=8,D=4的超引力张量体系是必不可少的,与它的U-对偶群E(7(+7))相一致。

英文摘要:

We study the tensor gauge fields ("notophs") of ungauged N=8 D=4 supergravity in superspace. These are described by 2-form potentials in the adjoint representation of G=E(7(+7)). The consistency of the natural candidates for the superspace constraints for their field strengths fixes the form of the generalized Bianchi identities and also requires the potentials with indices of G/H=E(7(+7))/SU(8) generators to be dual to the scalars of the N=8,D=4 supergravity multiplet. In contrast, the field strengths of the 2-form potentials corresponding to the SU(8) generators are dual to fermionic bilinears, so that these potentials are auxiliary rather than physical fields. Their presence, however, is essential to formulate a tensor hierarchy of N=8,D=4 supergravity consistent with its U-duality group E(7(+7)).
