超对称非线性实现中的恒等式

Identities in Nonlinear Realizations of Supersymmetry

Haishan Liu, Hui Luo, Mingxing Luo, Liucheng Wang

摘要:

在本文中,我们强调,紫外超对称性破缺理论可以实现线性或非线性。这两种认识形成了紫外超对称性破缺理论的双重描述。在此观察的指导下,我们发现微妙的身份涉及Goldstino领域和物质领域的标准非线性实现从平凡的线性实现。标准非线性实现中相当复杂的被积函数被认为是全发散。特别地,仅涉及Goldstino场的恒等式揭示了Grassmann代数的自洽性。作为这些恒等式的一个应用,我们证明了当相应的线性Kahler势是固定的时,无论有无规范相互作用,非线性Kahler势都是唯一的。我们的恒等式选出了全发散项,并保证了这种唯一性。

英文摘要:

In this paper, we emphasize that a UV SUSY-breaking theory can be realized either linearly or nonlinearly. Both realizations form the dual descriptions of the UV SUSY-breaking theory. Guided by this observation, we find subtle identities involving the Goldstino field and matter fields in the standard nonlinear realization from trivial ones in the linear realization. Rather complicated integrands in the standard nonlinear realization are identified as total-divergences. Especially, identities only involving the Goldstino field reveal the self-consistency of the Grassmann algebra. As an application of these identities, we prove that the nonlinear Kahler potential without or with gauge interactions is unique, if the corresponding linear one is fixed. Our identities pick out the total-divergence terms and guarantee this uniqueness.
