Type-II backgrounds from deformed coset CFTs

High Energy Physics - Theory 2025-06-23 v2

Abstract

We construct a plethora of type-II supergravity solutions featuring AdS factors in their geometries, derived from integrable deformations of coset CFTs. Specifically, we uplift the λ\lambda-deformed models of SO(4)k/SO(3)kSO(4)_k/SO(3)_k and SO(5)k/SO(4)kSO(5)_k/SO(4)_k, including the non-compact version of the latter. Requiring reality for the backgrounds imposes bounds on the deformation parameter. As a result, some of the solutions do not admit non-Abelian T-dual limit.
