Interaction of $\pi$ and $K$ mesons and nucleons in the model of composite superconformal strings

We construct a model of composite superconformal strings to describe hadron interaction amplitudes and the hadron spectrum. It belongs to a new class of dual (string) models and falls outside the scope of the usual approaches. In the framework of this model, the ordinary hadron scale of the order of $1$ GeV$^{-2}$ is regarded as a string scale $\alpha'$. The supersymmetry requirements are satisfied only on the two-dimensional world surface. We calculate interaction amplitudes of $\pi$ and $K$ mesons in the framework of the theory. We find a method for removing the baryon parity degeneracy.
