A free field perspective of λ-deformed coset CFT’s

Abstract We continue our study of λ-deformed σ-models by setting up a 1 k $$ \frac{1}{k} $$ perturbative expansion around the free field point for cosets, in particular for the λ-deformed SU(2)/U(1) coset CFT. We construct an interacting field theory in which all deformation effects are manifestly e...
