Heavy-Meson Observables via Dyson-Schwinger Equations
  We summarise a Dyson-Schwinger-equation-based calculation of an extensive range of light- and heavy-meson observables, characterised by heavy-meson leptonic decays, semileptonic heavy-to-heavy and heavy-to-light transitions, radiative and strong decays, and the rare flavour-changing neutral-current process. In the calculation the heavy-quark mass functions are approximated by constants, interpreted as their constituent mass.
