Abstract
We describe a deformation of the principal chiral model (with an evendimensional target space G) by a B-field proportional to the Kähler form on the target space. The equations of motion of the deformed model admit a zero-curvature representation. As a simplest example, we consider the case of G = S 1 × S 3. We also apply a variant of the construction to a deformation of the AdS 3 × S 3 × S 1 (super-)σ-model.
