四维离壳超共形高自旋多重态

Off-shell superconformal higher spin multiplets in four dimensions

Sergei M. Kuzenko, Ruben Manvelyan, Stefan Theisen

摘要:

我们制定了离壳N=1超共形高自旋多重态在四维时空,并简要讨论了它们的耦合共形超引力。作为一个例子,我们明确地计算了超共形引力子多重态与共形超引力的耦合。相应的作用量是超外尔不变量的任意超引力背景。然而,只有当超对称巴赫张量为零时,它才是规范不变的。这类似于弯曲背景下的线性共形超引力。

英文摘要:

We formulate off-shell N=1 superconformal higher spin multiplets in four spacetime dimensions and briefly discuss their coupling to conformal supergravity. As an example, we explicitly work out the coupling of the superconformal gravitino multiplet to conformal supergravity. The corresponding action is super-Weyl invariant for arbitrary supergravity backgrounds. However, it is gauge invariant only if the supersymmetric Bach tensor vanishes. This is similar to linearised conformal supergravity in curved background.
