Title: 4D Chern-Simons theory with auxiliary fields
Abstract:
Recently, an integrable deformation of the primal chiral model using auxiliary fields,
called the auxiliary field sigma model (AFSM), was proposed by C. Ferko and L. Smith [arXiv:2405.05899 [hep-th]]. This integrable deformation includes arbitrary functions, and depending on how they are chosen, TTbar deformation and root TTbar deformation can also be described.
In this talk, I will talk about the extension of 4D Chern-Simons theory, which is expected to be a unified theory of integrable models, by including auxiliary fields so that AFSM can be derived. This talk is based on arXiv2407.02204 [hep-th], a joint work with Osamu Fukushima (RIKEN iTHEMS).
