Tetraquark and two-meson states at large $$N_{\mathrm {c}}$$ N c
Abstract Considering four-point correlation functions of color-singlet quark bilinears, we investigate, in the large- $$N_{\mathrm {c}}$$ N c limit of QCD, the subleading diagrams that involve, in the s-channel of meson–meson scattering amplitudes, two-quark–two-antiquark intermediate states. The la...
