The Goldstino Brane, the Constrained Superfields and Matter in N=1 Supergravity

Igor Bandos, Markus Heller, Sergei M. Kuzenko, Luca Martucci, Dmitri Sorokin

摘要:

我们表明,不同的(膜和约束超场)的描述耦合到N=1,D=4的超引力与物质产生类似的宽类模型自发破缺的局部超对称性,并讨论不同的配方之间的关系。与具有不可约约束超场的公式一样,几何Goldstino膜方法具有明显的离壳超对称性而无需引入辅助场的优点。它提供了幂零超场约束的显式解,并避免了辅助场的非高斯积分问题。我们描述了超对称破缺扇区,包括戈德斯坦诺和其他非超对称物质,超引力和物质超多重态的一般耦合。在各种例子中,我们讨论了goldstino膜的引力子质量项的贡献和超对称化的反D3膜的贡献的有效理论的IIB型翘曲通量紧致化。

英文摘要:

We show that different (brane and constrained superfield) descriptions for the Volkov-Akulov goldstino coupled to N=1, D=4 supergravity with matter produce similar wide classes of models with spontaneously broken local supersymmetry and discuss the relation between the different formulations. As with the formulations with irreducible constrained superfields, the geometric goldstino brane approach has the advantage of being manifestly off-shell supersymmetric without the need to introduce auxiliary fields. It provides an explicit solution of the nilpotent superfield constraints and avoids issues with non-Gaussian integration of auxiliary fields. We describe general couplings of the supersymmetry breaking sector, including the goldstino and other non-supersymmetric matter, to supergravity and matter supermultiplets. Among various examples, we discuss a goldstino brane contribution to the gravitino mass term and the supersymmetrization of the anti-D3-brane contribution to the effective theory of type IIB warped flux compactifications.
