We concentrate here on the scalar sector. In the limit of large $N$ this model coincides with integrable spin chain while at finite N it has nontrivial chain splitting and joining interaction.6 pages, 2 figures, Cotribution to the XI International Conference on Symmetry Methods in Physics (SYMPHYS-11)High Energy Physics - Theorytext
