5维超引力与射影超空间

5D Supergravity and Projective Superspace

Sergei M. Kuzenko, Gabriele Tartaglino-Mazzucchelli

摘要:

本文是我们早期工作arXiv:0710.3440的姊妹篇,其中提出了五维物质耦合简单超引力的投影超空间公式。对于Howe在1981年提出的5D N=1超引力的最小多重态,我们给出了Bianchi恒等式的完整解.弯曲的超空间的几何形状,允许存在一个大家庭的离壳超多重态,可用于描述超对称的物质,包括矢量多重态和超多重态。我们制定了一个明显的局部超对称作用原理。它的自然属性原来是在所谓的射影变换下的辅助isotwistor变量的不变性。然后,我们证明,投影不变性允许一个唯一的恢复行动功能的Wess-Zumino规范。后一种作用非常适合于将超重力物质系统还原为组件。

英文摘要:

This paper is a companion to our earlier work arXiv:0710.3440 in which the projective superspace formulation for matter-coupled simple supergravity in five dimensions was presented. For the minimal multiplet of 5D N=1 supergravity introduced by Howe in 1981, we give a complete solution of the Bianchi identities. The geometry of curved superspace is shown to allow the existence of a large family of off-shell supermultiplets that can be used to describe supersymmetric matter, including vector multiplets and hypermultiplets. We formulate a manifestly locally supersymmetric action principle. Its natural property turns out to be the invariance under so-called projective transformations of the auxiliary isotwistor variables. We then demonstrate that the projective invariance allows one to uniquely restore the action functional in a Wess-Zumino gauge. The latter action is well-suited for reducing the supergravity-matter systems to components.
