我们在定向折叠圆锥形褶皱背景下的一堆 N 个物理膜和 M 个分数 D3 膜上研究 = 1 Sp(2N+2M) × Sp(2N) 规范理论。重力对偶是 AdS5 × T11 的 IIB 型东方褶皱(某些背景通量打开),包含一个 O7 平面和 8 个 D7 膜。在共形情况下 (M = 0),我们认为位于 8 个 D7 膜和 O7 平面上的 α'2 项应该对体场超重力运动方程的贡献消失。在级联情况下 (M≠0),我们认为 α'2 项会引起校正,在对偶 Sp(2N+M) × Sp(2N) 规范理论中,可以将其解释为对物质场的反常维度的校正。
We study the = 1 Sp(2N+2M) × Sp(2N) gauge theory on a stack of N physical and M fractional D3-branes in the background of an orientifolded conifold. The gravity dual is a type-IIB orientifold of AdS5 × T11 (with certain background fluxes turned on) containing an O7-plane and 8 D7-branes. In the conformal case (M = 0), we argue that the α'2-terms localized on the 8 D7-branes and the O7-plane should give vanishing contributions to the supergravity equations of motion for the bulk fields. In the cascading case (M≠0), we argue that the α'2-terms give rise to corrections which in the dual Sp(2N+M) × Sp(2N) gauge theory can be interpreted as corrections to the anomalous dimensions of the matter fields.
