    "abstract": "Two-body bound states such as mesons are described by solutions of the\nBethe-Salpeter equation. We discuss recent results for the pseudoscalar and\nvector meson masses and leptonic decay constants, ranging from pions up to\nc\\bar{c} bound states. Our results are in good agreement with data. Essential\nin these calculation is a momentum-dependent quark mass function, which evolves\nfrom a constituent-quark mass in the infrared region to a current-quark mass in\nthe perturbative region. In addition to the mass spectrum, we review the\nelectromagnetic form factors of the light mesons. Electromagnetic current\nconservation is manifest and the influence of intermediate vector mesons is\nincorporated self-consistently. The results for the pion form factor are in\nexcellent agreement with experiment.",
