Integrable sigma models and 2-loop RG flow
Abstract Following arXiv:1907.04737 , we continue our investigation of the relation between the renormalizability (with finitely many couplings) and integrability in 2d σ- models. We focus on the “λ-model,” an integrable model associated to a group or symmetric space and containing as special limits...
