Sigma models with local couplings: a new integrability -- RG flow connection
Ben Hoare, Nat Levine, Arkady A. Tseytlin
We consider several classes of -models (on groups and symmetric spaces, -models, -models) with local couplings that may depend on the 2d coordinates, e.g. on time . We…
Integrable sigma models and 2-loop RG flow
Ben Hoare, Nat Levine, Arkady A. Tseytlin
Following arXiv:1907.04737, we continue our investigation of the relation between the renormalizability (with finitely many couplings) and integrability in 2d -models. We focus…
Integrable 2d sigma models: quantum corrections to geometry from RG flow
Ben Hoare, Nat Levine, Arkady A. Tseytlin
Classically integrable -models are known to be solutions of the 1-loop RG equations, or "Ricci flow", with only a few couplings running. In some of the simplest examples of inte…
On the massless tree-level S-matrix in 2d sigma models
Ben Hoare, Nat Levine, Arkady A. Tseytlin
Motivated by the search for new integrable string models, we study the properties of massless tree-level S-matrices for 2d sigma models expanded near the trivial vacuum. We find th…
