Abstract

We examine integrable λ-deformations of SO(n+1)/SO(n) coset CFTs and their analytic continuations. We provide an interpretation of the deformation as a squashing of the corresponding coset σ-model's target space. We realise the λ-deformation for n=5 case as a solution to supergravity supported...

Abstract: We examine integrable λ-deformations of SO(n+1)/SO(n) coset CFTs and their analytic continuations. We provide an interpretation of the deformation as a squashing of the corresponding coset σ-model's target space. We realise the λ-deformation for n=5 case as a solution to supergravity supported by non-vanishing five-form and dilaton. This interpolates between the coset CFT SO(4,2)/SO(4,1)×SO(6)/SO(5) constructed as a gauged WZW model and the non-Abelian T-dual of the AdS5×S5 spacetime.
