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…
Supersymmetric Liouville theory in AdS and AdS/CFT
Matteo Beccaria, Hongliang Jiang, Arkady A. Tseytlin
In a series of recent papers, a special kind of AdS/CFT duality was observed: the boundary correlators of elementary fields that appear in the Lagrangian of a 2d conformal…
Non-abelian Toda theory on AdS and AdS/CFT duality
Matteo Beccaria, Hongliang Jiang, Arkady A. Tseytlin
It was recently observed that boundary correlators of the elementary scalar field of the Liouville theory on AdS background are the same (up to a non-trivial proportionality co…
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…
One-loop beta-functions in 4-derivative gauge theory in 6 dimensions
Lorenzo Casarin, Arkady A. Tseytlin
A classically scale-invariant 6d analog of the 4d Yang-Mills theory is the 4-derivative gauge theory with two independent couplings. Motivated by a search for…
On boundary correlators in Liouville theory on AdS
Matteo Beccaria, Arkady A. Tseytlin
We consider the Liouville theory in fixed Euclidean AdS background. Expanded near the minimum of the potential the elementary field has mass squared 2 and (assuming the standar…
