All-loop anomalous dimensions in integrable $λ$ -deformed $σ$ -models

George Georgiou, Konstantinos Sfetsos, Konstantinos Siampos

We calculate the all-loop anomalous dimensions of current operators in $λ$ -deformed $σ$ -models. For the isotropic integrable deformation and for a semi-simple group $G$ we compute…

Generalised integrable $λ$ - and $η$ -deformations and their relation

Konstantinos Sfetsos, Konstantinos Siampos, Daniel C. Thompson

We construct two-parameter families of integrable $λ$ -deformations of two-dimensional field theories. These interpolate between a CFT (a WZW/gauged WZW model) and the non-Abelian T…

Integrable $λ$ -deformations: Squashing Coset CFTs and $A d S_{5} \times S^{5}$

Saskia Demulder, Konstantinos Sfetsos, Daniel C. Thompson

We examine integrable $λ$ -deformations of $S O (n + 1) / S O (n)$ coset CFTs and their analytic continuations. We provide an interpretation of the deformation as a squashing of the corresp…
