5维超引力中的超外尔不变性

Super-Weyl invariance in 5D supergravity

Sergei M. Kuzenko, Gabriele Tartaglino-Mazzucchelli

摘要:

本文提出了N=1共形超引力的Weyl多重态在五维空间中的一个超空间公式。相应的超空间约束在由实标量参数生成的超外尔变换下是不变的。最小超引力多重态是由豪在1981年提出的,如果将外尔多重态耦合到阿贝尔向量多重态,然后通过施加规范条件W=1来打破超外尔不变性,则出现W是向量多重态的场强。超空间的几何允许存在一个大家庭的离壳超多重态,拥有唯一确定的超外尔变换定律,并可用于描述超对称物质。许多这样的超多重态并没有出现在超共形张量演算中。我们制定了一个明显的局部超对称和超外尔不变的作用原理。在超外尔规范W=1中,这个作用量简化为arXiv:0712.3102中构造的作用量。我们还提出了一个超空间制定的Weyl多重峰。

英文摘要:

We propose a superspace formulation for the Weyl multiplet of N=1 conformal supergravity in five dimensions. The corresponding superspace constraints are invariant under super-Weyl transformations generated by a real scalar parameter. The minimal supergravity multiplet, which was introduced by Howe in 1981, emerges if one couples the Weyl multiplet to an Abelian vector multiplet and then breaks the super-Weyl invariance by imposing the gauge condition W=1, with W the field strength of the vector multiplet. The geometry of superspace is shown to allow the existence of a large family of off-shell supermultiplets that possess uniquely determined super-Weyl transformation laws and can be used to describe supersymmetric matter. Many of these supermultiplets have not appeared within the superconformal tensor calculus. We formulate a manifestly locally supersymmetric and super-Weyl invariant action principle. In the super-Weyl gauge W=1, this action reduces to that constructed in arXiv:0712.3102. We also present a superspace formulation for the dilaton Weyl multiplet.
