摘要：

Clean predictions are presented for all the spin-averaged heavy-light meson spectroscopies. A new symmetry is identified wherein the energy eigenstates have a universal dependence on both the light and heavy quark masses. This universality is used in an efficient analysis of these mesons within the QCD string or flux tube picture. We give unique predictions for all the D, D-s, B, and B-s type mesons in terms of just four measured quantities.
