    "abstract": "We study pseudoscalar and scalar mesons using a practical and symmetry\npreserving truncation of QCD\u0027s Dyson-Schwinger equations. We investigate and\ncompare properties of ground and radially excited meson states. In addition to\nexact results for radial meson excitations we also present results for meson\nmasses and decay constants from the chiral limit up to the charm-quark mass, e.\ng., the mass of the chi_{c0} (2P) meson.",
