Tetraquark and two-meson states at large [Formula: see text]

Considering four-point correlation functions of color-singlet quark bilinears, we investigate, in the large-[Formula: see text] limit of QCD, the subleading diagrams that involve, in the s-channel of meson–meson scattering amplitudes, two-quark–two-antiquark intermediate states. The latter contribut...
