The 1/N_c arguments are developed to classify the hadronic states in the correlators. Arguments applied to the σ meson correlator enable to separate the instanton, glueball, and, in particular, the ππ scattering states by 1/N_c from both 2q and 4q correlators. The bare resonance pole with no mixing effects are analyzed with the QCD sum rules (QSR). The results suggest the existence of nontrivial correlation for the mass reduction of 4q system.
