Compositeness for the $N^{ast}$ and $Delta ^{ast}$ resonances from the scattering amplitude

Sekihara, Takayasu

The meson-baryon components for the $N^{ast}$ and $Delta ^{ast}$ resonances can be investigated in terms of the compositeness, which is defined as the norm of the two-body wave function from the meson-baryon scattering amplitudes. For this purpose I first show that one can calculate the two-body wave function from the scattering amplitudes (not by the Schrodinger equation) by considering several schematic models. Then I explain my plan to evaluate $N^{ast}$ / $Delta ^{ast}$ compositeness from the scattering amplitudes, which has been determined precisely in the partial wave analyses.
