关于Goldstino作用量及其对称性

On the Goldstino actions and their symmetries

Sergei M. Kuzenko, Simon J. Tyler

摘要:

从Akulov-Volkov(AV)作用量出发,我们计算了所有形式为λ-> λ' = λ+ O(λ^3)的场变换的有限维李群G,它保持了低能类Goldstino作用量的泛函结构。与G相关联的是它的AV作用的平凡对称的十二参数子群H。陪集空间G/H自然地与所有Goldstino模型的空间等同。然后,我们应用我们的建设,研究五个不同的Goldstino行动在文献中的属性。利用最一般的字段重定义派生,我们发现所有五种情况下之间的显式映射。在每一种情况下,由于Goldstino作用中固有的平凡对称性,这些映射中存在12个参数的自由。最后,通过使用AV超对称的推进,我们找到了其他五个行动的离壳非线性超对称变换,并与通常与这些行动。

英文摘要:

Starting from the Akulov-Volkov (AV) action, we compute a finite-dimensional Lie group G of all field transformations of the form λ-> λ' = λ+ O(λ^3) which preserve the functional structure of low-energy Goldstino-like actions. Associated with G is its twelve-parameter subgroup H of trivial symmetries of the AV action. The coset space G/H is naturally identified with the space of all Goldstino models. We then apply our construction to study the properties of five different Goldstino actions available in the literature. Making use of the most general field redefinition derived, we find explicit maps between all five cases. In each case there is a twelve- parameter freedom in these maps due to trivial symmetries inherent in the Goldstino actions. Finally, by using the pushforward of the AV supersymmetry, we find the off-shell nonlinear supersymmetry transformations of the other five actions and compare to those normally associated with these actions.
