| dc.description | Systematic $1/N_c$ counting of correlators is performed to directly relate quark-gluon dynamics to qualitatively different hadronic states order by order. Both 2q and 4q correlators of $σ$ quanta are analyzed with $1/N_c$ separation of the instanton, glueball, and in particular, two meson scattering states. The {\it bare} resonance pole with no mixing effects are studied with the QCD sum rules (QSR). The bare mass relation for large $N_c$ mesons, $m_ρ<m_{4q}^{I=J=0}<m_{2q}^{I=J=0}$, is derived. The firm theoretical ground of the QSR at the leading $1/N_{c}$ analyses is also emphasized. | |
