SUMMARY
The relationship between the vertex function and wave function of mesons is complex and not straightforward. Vertex functions are utilized in renormalizable field theories, particularly in higher-order perturbation theory, as corrections to vertices in Feynman diagrams. However, mesons are not treated as fundamental particles in the standard model, which focuses on quarks and leptons. The Bethe-Salpeter wave function can express the hadron quark-antiquark vertex function of mesons, as noted in the journal by A.N. Mitra and S. Bhatnagar.
