E7(7)N=2背景的制剂

E7(7) formulation of N=2 backgrounds

Mariana Grana, Jan Louis, Aaron Sim, Daniel Waldram

摘要:

本文用U-对偶群E7(7)下的量变换重新表述了II型弦论中N=2的超引力背景。特别是,我们结合起来的拉蒙-拉蒙标量自由度与O(6,6)纯旋量的Neveu-Schwarz部门考虑广义几何的扩展版本。给出了描述向量和超重态的模空间的Kahler势和超Kahler势的E7(7)不变表达式,证明了它们都对应于标准的E7(7)陪集空间.我们还找到了定义标量势的Killing前势的E7(7)表达式,并讨论了在此形式下N=1真空的方程。

英文摘要:

In this paper we reformulate N=2 supergravity backgrounds arising in type II string theory in terms of quantities transforming under the U-duality group E7(7). In particular we combine the Ramond--Ramond scalar degrees of freedom together with the O(6,6) pure spinors which govern the Neveu-Schwarz sector by considering an extended version of generalised geometry. We give E7(7)-invariant expressions for the Kahler and hyperkahler potentials describing the moduli space of vector and hypermultiplets, demonstrating that both correspond to standard E7(7) coset spaces. We also find E7(7) expressions for the Killing prepotentials defining the scalar potential, and discuss the equations governing N=1 vacua in this formalism.
