摘要:

N=2全局超对称性部分破缺的一个必要条件是存在场变换的非线性变形,而这种变形不能由辅助场的背景值产生。这项工作研究的最简单的这些变形已经发生在N=1的全球超对称性,其耦合到超引力。它可以看作是阿贝尔规范多重态的D-辅助实场的虚常数位移。我们展示了这种变形如何描述费耶特-伊利奥普洛斯项的磁对偶,这一结果在超引力中仍然有效,使用其新的最小公式。局域超对称性和形变导致正的宇宙学常数。此外,变形的U(1)麦克斯韦理论耦合到超引力描述了在消除辅助场的R对称性的测量,由1976年的弗里德曼模型实现。为此,我们在超共形张量演算中构造了手征旋量多重态,并利用它来描述与U(1)多重态耦合的新极小超引力.我们还讨论了弯曲超空间中的变形Maxwell理论。

英文摘要:

A necessary condition for partial breaking of N=2 global supersymmetry is the presence of nonlinear deformations of the field transformations which cannot be generated by background values of auxiliary fields. This work studies the simplest of these deformations which already occurs in N=1 global supersymmetry, and its coupling to supergravity. It can be viewed as an imaginary constant shift of the D-auxiliary real field of an abelian gauge multiplet. We show how this deformation describes the magnetic dual of a Fayet-Iliopoulos term, a result that remains valid in supergravity, using its new-minimal formulation. Local supersymmetry and the deformation induce a positive cosmological constant. Moreover, the deformed U(1) Maxwell theory coupled to supergravity describes upon elimination of the auxiliary fields the gauging of R-symmetry, realised by the Freedman model of 1976. To this end, we construct the chiral spinor multiplet in superconformal tensor calculus by working out explicitly its transformation rules and use it for an alternative description of the new-minimal supergravity coupled to a U(1) multiplet. We also discuss the deformed Maxwell theory in curved superspace.
