Looking for the Separation of Variables in a 4D CFT

Some higher-dimensional CFTs, such as N=4 Super Yang-Mills (SYM) theory, are believed to possess the mathematical structures of integrability – however, it is far from completely understood how to solve these models completely. In this talk, I will discuss the role of the Separation of Variables, an expected powerful property of integrable systems, in this context. I will present some recent theoretical advances on the SoV method, and how these new techniques can be employed to compute nontrivial observables in a 4D CFT, the “fishnet” theory – a close cousin of N=4 SYM. The talk is based on the work hep-th/2103.15800 in collaboration with N. Gromov and F. Levkovich-Maslyuk.
