Two-body wave functions and compositeness from scattering amplitudes. II. Application to the physical N* and Δ* resonances

The meson-baryon molecular components for the ${N}^{*}$ and ${\mathrm{\ensuremath{\Delta}}}^{*}$ resonances are investigated in terms of compositeness, which is defined as norm two-body wave function from scattering amplitudes. amplitudes constructed a $\ensuremath{\pi}N\text{\ensuremath{-}}\ensuremath{\eta}N\text{\ensuremath{-}}\ensuremath{\sigma}N\text{\ensuremath{-}}\ensuremath{\rho}N\text{\ensuremath{-}}\ensuremath{\pi}\mathrm{\ensuremath{\Delta}}$ coupled-channels problem meson exchange model together with several bare states, parameters fitted so to reproduce on-shell $\ensuremath{\pi}N$ partial up center-of-mass energy $1.9\phantom{\rule{0.16em}{0ex}}\mathrm{GeV}$ orbital angular momentum $L\ensuremath{\le}2$. As result, Roper resonance $N(1440)$ found be dominated by $\ensuremath{\sigma}N$ while bare-state contribution small. squared functions coordinate space imply that both channels separation between baryon about more than $1\phantom{\rule{0.16em}{0ex}}\mathrm{fm}$ resonance. On other hand, dominant not observed any present model, although they have some fractions clouds.
