我们在 $AdS_5\times S^5/\Zop_2$ 方向上找到了经典的开弦解，其角动量沿着五球体。这些解的能量在 $\lambda$ 的积分幂上有扩展，并通过 $J$（总角动量）的逆幂抑制西格玛模型校正。这给出了在 ${\cal N}=2$ $Sp(N)$ Super-Yang-Mills 物质理论的大 $N$ 限制中算子的精确反常维度的预测。我们还找到了开弦解和闭弦解之间的简单映射。这给出了双规范理论中单迹算子和双夸克算子的反常维度之间的全环平面关系的预测。
We find classical open string solutions in the $AdS_5\times S^5/\Zop_2$ orientifold with angular momenta along the five-sphere. The energy of these solutions has an expansion in integral powers of $\lambda$ with sigma-model corrections suppressed by inverse powers of $J$ - the total angular momentum. This gives a prediction for the exact anomalous dimensions of operators in the large $N$ limit of an ${\cal N}=2$ $Sp(N)$ Super-Yang-Mills theory with matter. We also find a simple map between open and closed string solutions. This gives a prediction for an all-loop planar relationship between the anomalous dimensions of single-trace and two-quark operators in the dual gauge theory.
