Oplane couplings at order α'^{2}: one RR field strength
Abstract
It is known that the anomalous ChernSimons (CS) coupling of O_{p}plane is not consistent with the Tduality transformations. Compatibility of this coupling with the Tduality requires the inclusion of couplings involving one RR field strength. In this paper we find such couplings at order α'^{2}. By requiring the RR and NSNS gauge invariances, we first find all independent couplings at order α'^{2}. There are 1, 6, 28, 20, 19, 2 couplings corresponding to the RR field strengths F^{(p4)}, F^{(p2)}, F^{(p)}, F^{(p+2)}, F^{(p+4)} and F^{(p+6)}, respectively. We then impose the Tduality constraint on these couplings and on the CS coupling C^{(p3)} ∧ R ∧ R at order α'^{2} to fix their corresponding coefficients. The Tduality constraint fixes all coefficients in terms of the CS coefficient. They are fully consistent with the partial couplings that have been already found in the literature by the Smatrix method.
