Description
A novel classically integrable model is proposed. It is a deformation of a two-dimensional principal chiral or WZW model, embedded into a heterotic σ-model. This is inspired by the bosonic part of the heterotic σ-model and its recent Hamiltonian formulation in terms of O(d,d+n)-generalised geometry. Classical integrability is shown by construction of a Lax pair and a classical r-matrix. I briefly discuss the non-trivial non-deformation limit and the deformed backgrounds as solutions of heterotic supergravity.
