Riemann曲面上6d极小SCFT的紧化

Compactification of 6d minimal SCFTs on Riemann surfaces

Shlomo S. Razamat, Gabi Zafrir

摘要:

研究了具有一维张量分支且不具有连续整体对称性的N=(1,0)6dSCFT的穿孔Riemann曲面上的紧化.这种模型在张量分支上的有效描述是根据具有解耦张量的纯规范理论。对于一般的黎曼曲面,所得到的四维理论预期具有N=1的超对称性。我们计算的异常预期从所得到的4D理论通过集成的异常多项式的6D理论上的黎曼曲面。对于规范群为SU(3)和SO(8)的6d规范模型,我们进一步提出了4d理论的场论结构。对于6d SU(3)理论,我们认为四维理论是具有SU(3)规范节点和自由手征场的箭图。从6d SO(8)规范理论得到的理论是具有SU(4)规范群的箭图和具有一半R荷的手征场。在最后一种情况下,为一般黎曼曲面构建的理论涉及对强耦合时出现的对称性进行测量。模型的共形流形由规范耦合和重子超势构成。我们通过匹配黎曼曲面的复结构模的共形流形的尺寸,匹配六维和四维之间的异常,并检查与曲面的不同裤子分解相关的对偶来支持我们的计算。作为结果的一个简单应用,我们猜想四维九味SU(3)规范理论有一个对偶群作用在七维共形流形上,而七维共形流形是球的十点映射类群.

英文摘要:

We study compactifications on Riemann surfaces with punctures of N=(1,0) 6d SCFTs with a one dimensional tensor branch and no continuous global symmetries. The effective description of such models on the tensor branch is in terms of pure gauge theories with decoupled tensor. For generic Riemann surfaces, the resulting theories in four dimensions are expected to have N=1 supersymmetry. We compute the anomalies expected from the resulting 4d theories by integrating the anomaly polynomial of the 6d theory on the Riemann surface. For the cases with 6d gauge models with gauge groups SU(3) and SO(8) we further propose a field theory construction for the resulting 4d theories. For the 6d SU(3) theory, we argue that the theories in four dimensions are quivers with SU(3) gauge nodes and free chiral fields. The theories one obtains from the 6d SO(8) gauge theory are quivers with SU(4) gauge groups and chiral fields with R charge a half. In the last case the theories constructed for general Riemann surfaces involve gauging of symmetries appearing at strong coupling. The conformal manifolds of the models are constructed from gauge couplings and baryonic superpotentials. We support our conjectures by matching the dimensions of the conformal manifolds with complex structure moduli of the Riemann surfaces, matching anomalies between six and four dimensions, and checking the dualities related to different pair of pants decompositions of the surfaces. As a simple application of the results we conjecture that SU(3) gauge theory with nine flavors in four dimensions has a duality group acting on the seven dimensional conformal manifold which is the mapping class group of sphere with ten marked points.
