对立项与对偶项

Counterterms vs. Dualities

Guillaume Bossard, Hermann Nicolai

摘要:

我们研究并澄清了超引力和弦论有效作用量的高阶修正的相互兼容性以及这些理论的非线性对偶对称性。从一个传统的树级行动导致对偶不变的运动方程,我们展示了如何容纳对偶不变的counterterterms作为泛函的电场和磁场在微扰展开,并从中推导出一个非多项式真正的行动满足Gaillard-Zumino约束。在非协变的Henneaux-Teitelboim形式主义中存在一个相应的一致性约束,它确保了人们总是可以通过扰动求解这个函数恒等式来恢复同构不变性。我们举例说明这个过程如何适用于麦克斯韦理论中的R^2 \nabla F \nabla F和F^4反项。

英文摘要:

We investigate and clarify the mutual compatibility of the higher order corrections arising in supergravity and string theory effective actions and the non-linear duality symmetries of these theories. Starting from a conventional tree level action leading to duality invariant equations of motion, we show how to accommodate duality invariant counterterms given as functionals of both electric and magnetic fields in a perturbative expansion, and to deduce from them a non-polynomial bona fide action satisfying the Gaillard-Zumino constraint. There exists a corresponding consistency constraint in the non-covariant Henneaux-Teitelboim formalism which ensures that one can always restore diffeomorphism invariance by perturbatively solving this functional identity. We illustrate how this procedure works for the R^2 \nabla F \nabla F and F^4 counterterms in Maxwell theory.
