$α'^2$阶玻色弦论的$O(25,25)$对称性

$O(25,25)$ symmetry of bosonic string theory at order $α'^2$

Mohammad R. Garousi

摘要:

最近已经观察到,把$O(1,1)$对称性强加在弦论经典有效作用量的圆约化上,可以把玻色弦论的有效作用量固定在$α'^2$级,直到一个整体因子。在本文中,我们使用宇宙约化的作用,并表明,直到一维场的重新定义和总的衍生条款,它可以写在$O(25,25)$不变的形式提出的Hohm和Zwiebach。

英文摘要:

It has been recently observed that the imposition of the $O(1,1)$ symmetry on the circle reduction of the classical effective action of string theory, can fix the effective action of the bosonic string theory at order $α'^2$, up to an overall factor. In this paper, we use the cosmological reduction on the action and show that, up to one-dimensional field redefinitions and total derivative terms, it can be written in the $O(25,25)$-invariant form proposed by Hohm and Zwiebach.
