近日,英国伦敦玛丽女王大学的Hongliang Jiang及其研究团队取得一项新进展。经过不懈努力,他们通过表示理论提出从自由场到相互作用的超共形场论。相关研究成果已于2024年8月29日在国际知名学术期刊《高能物理杂志》上发表。
该研究团队提出了一个问题:是否可能从自由场论中的(连续变形)表示出发,构造出与局域性兼容的、具有八个庞加莱超荷的超共形代数的任意幺正多重态。研究人员在二维、三维和五维空间中回答了这个问题。在四维空间中,研究人员则借助于一系列复杂但自洽的猜想。
如果这些猜想正确,那么它们将对任何局域幺正四维N=2超共形场论中的短多重态,以及一系列不寻常的相关顶点代数,产生各种新的非微扰约束。在研究过程中,研究人员将他们的结果与理论空间中的变形性质联系起来。

Title: From free fields to interacting SCFTs via representation theory

Abstract: We ask when it is possible to construct arbitrary unitary multiplets of the superconformal algebra with eight Poincaré supercharges that are compatible with locality from (continuous deformations of) representations in free field theories. We answer this question in two, three, and five dimensions. In four dimensions, we resort to an intricate but self-consistent web of conjectures. If correct, these conjectures imply various new non-perturbative constraints on short multiplets in any local unitary 4d N = 2 superconformal field theory and on an unusual set of related vertex algebras. Throughout, we connect our results with properties of deformations in the space of theories.
