Field theory and λ-deformations: Expanding around the identity
We explore the structure of the λ-deformed σ-model action by setting up a perturbative expansion around the free field point corresponding to the identity group element. We include all field interaction terms up to sixth order. We compute the two- and three-point functions of current and primary fie...
