复杂的三种形式的超重力和膜

Complex three-form supergravity and membranes

Sergei M. Kuzenko, Gabriele Tartaglino-Mazzucchelli

摘要:

四维${\cal N}=1$超引力的旧最小公式存在两种变体,其中两个辅助标量中的一个或每一个都被规范三形式的场强所取代。这些理论分别被称为三形式超引力和复合三形式超引力。对于它们中的每一个,我们提出了一个超外尔不变耦合的超引力的超膜,并证明由此产生的作用的卡帕不变性。在三种形式超引力的情况下,我们证明了所构造的作用量可以简化为Ovrut和Walnut在20年前所给出的作用量,在这种作用量中,补偿的三种形式超场被设置为常数。

英文摘要:

There exist two variants of the old minimal formulation for ${\cal N}=1$ supergravity in four dimensions, in which one or each of the two auxiliary scalars is replaced by the field strength of a gauge three-form. These theories are known as three-form supergravity and complex three-form supergravity, respectively. For each of them, we present a super-Weyl invariant coupling of supergravity to the supermembrane and prove kappa-invariance of the resulting action. In the case of three-form supergravity, we demonstrate that the action constructed reduces to that given by Ovrut and Waldram twenty years ago upon imposing a super-Weyl gauge in which the compensating three-form superfield is set to a constant.
