Title : ( O(9,9) symmetry of NS-NS couplings at order α′3 )
Authors: Mohammad Reza Garousi ,
Full TextAbstract
Recently, imposing the $O(1,1)$ symmetry on the circle reduction of the classical effective action of string theory, we have found all NS-NS couplings of type II superstring theories at order $\\\\\\\\alpha\\\\\\\'^3$. In this paper we use the cosmological reduction on the couplings and show that, up to one-dimensional field redefinitions and total derivative terms, they are invariant under the $O(9,9)$ transformations.
