Integrable $\lambda$-deformations: Squashing Coset CFTs and $Ad{S}_5\times S^5$

Saskia Demulder, Konstantinos Sfetsos, Daniel C. Thompson

We examine integrable $\lambda$-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 corresp…
