The exact C-function in integrable λ-deformed theories

The exact C-function in integrable λ-deformed theories

By employing CFT techniques, we show how to compute in the context of λ-deformations of current algebras and coset CFTs the exact in the deformation parameters C-function for a wide class of integrable theories that interpolate between a UV and an IR point. We explicitly consider RG flows for integr...
