Current-Current Deformations of Conformal Field Theories, and WZW Models
read the original abstract
Moduli spaces of conformal field theories corresponding to current-current deformations are discussed. For WZW models, CFT and sigma model considerations are compared. It is shown that current-current deformed WZW models have WZW-like sigma model descriptions with non-bi-invariant metrics, additional B-fields and a non-trivial dilaton.

$J\bar{J}$-deformation as a Riemann bilinear dressing
Reformulates J bar J deformation in CFTs as a Riemann bilinear dressing that converts perturbation theory into operator dressings and modular-invariant kernel integrals on Riemann surfaces.

$J\bar{J}$-deformation as a Riemann bilinear dressing
Reformulates J bar J deformation in CFTs as Riemann-bilinear operator dressing that preserves modular properties on Riemann surfaces and matches bare/renormalized perturbation theory.
