论文摘要
Using the assumption that the independent gauge invariant couplings on the world-volume of the non-perturbative objects in the string theory are independent of the background, we find the four and the six gauge field strength and/or the second fundamental form couplings on the world volume of a D$_p$-brane in the superstring theory at order $α'^2$ in the normalization that $F$ is dimensionless.我们通过考虑具有一个圆圈的特定背景并通过对独立耦合施加相应的T-偶合性约束来找到它们。特别是，我们发现该顺序有12+146个独立的仪表不变耦合，而T偶尔约束可以修复其中的150个。我们表明，这些耦合与文献中的部分结果完全一致。此比较还固定了其余的8个耦合。
Using the assumption that the independent gauge invariant couplings on the world-volume of the non-perturbative objects in the string theory are independent of the background, we find the four and the six gauge field strength and/or the second fundamental form couplings on the world volume of a D$_p$-brane in the superstring theory at order $α'^2$ in the normalization that $F$ is dimensionless. We have found them by considering the particular background which has one circle and by imposing the corresponding T-duality constraint on the independent couplings. In particular, we find that there are 12+146 independent gauge invariant couplings at this order, and the T-duality constraint can fix 150 of them. We show that these couplings are fully consistent with the partial results in the literature. This comparison also fixes the remaining 8 couplings.
