Query: Survey of heavy-meson observables   We employ a Dyson-Schwinger equation model to effect a unified and uniformly
accurate description of light- and heavy-meson observables, which we
characterise by heavy-meson leptonic decays, semileptonic heavy-to-heavy and
heavy-to-light transitions - B -> D*, D, rho, pi; D -> K*, K, pi, radiative and
strong decays - B(s)* -> B(s) gamma; D(s)* -> D(s) gamma, D pi, and the rare
B-> K* gamma flavour-changing neutral-current process. We elucidate the
heavy-quark limit of these processes and, using a model-independent mass
formula valid for all nonsinglet pseudoscalar mesons, demonstrate that their
mass rises linearly with the mass of their heaviest constituent. In our
numerical calculations we eschew a heavy-quark expansion and rely instead on
the observation that the dressed c,b-quark mass functions are well approximated
by a constant, interpreted as their constituent-mass: we find M_c=1.32 GeV and
M_b=4.65 GeV. The calculated heavy-meson leptonic decay constants and
transition form factors are a necessary element in the experimental
determination of CKM matrix elements. The results also show that this
framework, as employed hitherto, is well able to describe vector meson
polarisation observables.
