论文摘要
我们研究了大型级别（$ M \ rightarrow \ infty $）限制的统一Virasoro最小模型。在大型$ m $扰动理论中，我们发现了两个非平凡的IR固定点，它们在几个异常的维度和中心电荷中表现出非理性系数。对于$ n> 4 $的副本，我们表明，IR理论破坏了所有可能增强Virasoro代数的可能的电流，直至旋转10。这提供了有力的证据，表明IR固定点是紧凑，统一的，不合理的CFT的示例，具有最小的手性对称性。我们还分析了随着自旋越来越多的变性算子家族的异常尺寸矩阵。这些显示了进一步的非理性证据，并开始揭示领先的量子轨迹的形式。
We study coupled unitary Virasoro minimal models in the large rank ($m \rightarrow \infty$) limit. In large $m$ perturbation theory, we find two non-trivial IR fixed points which exhibit irrational coefficients in several anomalous dimensions and the central charge. For $N>4$ copies, we show that the IR theory breaks all possible currents that would otherwise enhance the Virasoro algebra, up to spin 10. This provides strong evidence that the IR fixed points are examples of compact, unitary, irrational CFTs with the minimal amount of chiral symmetry. We also analyze anomalous dimension matrices for a family of degenerate operators with increasing spin. These display further evidence of irrationality and begin to reveal the form of the leading quantum Regge trajectory.
