Description
A novel classically integrable model is proposed. It is a deformation of the two-dimensional principal chiral model, embedded into a heterotic σ-model. This is inspired by the bosonic part of the heterotic σ-model and its recent Hamiltonian formulation of the heterotic σ-model in terms of O(d,d+n)-generalised geometry. Classical integrability is shown by construction of a Lax pair and a classical R-matrix. Latter is almost of the canonical form with twist function and solves the classical Yang-Baxter equation.
