A detailed study of orbital and radial excited states in ${D,D}_{s},B,$ and ${B}_{s}$ systems is performed. The chiral quark model provides the framework for the calculation of pseudoscalar meson $(\ensuremath{\pi},K,\dots{})$ hadronic transitions among heavy-light excited and ground states. To calculate the excited states masses and wave functions, we must resort to a relativistic quark model. Our model includes the leading order corrections in ${1/m}_{(c,b)}$ (e.g., mixing). Numerical results for masses and light hadronic transition rates are compared to existing experimental data. The effective coupling of the chiral quark model can be determined by comparing with independent results from lattice simulations ${(g}_{A}^{8}=0.53\ifmmode\pm\else\textpm\fi{}0.11)$ or fitting to known widths ${(g}_{A}^{8}=0.82\ifmmode\pm\else\textpm\fi{}0.09).$

Hadronic molecules (2017, background): “…DK/D∗K molecular hypothesis: • Their masses are about 160 MeV and 70 MeV, respectively, below the predicted 0+ and 1+ charm-strange mesons by the Godfrey–Isgur quark model (Di Pierro and Eichten, 2001; Godfrey and Isgur, 1985), making them not easy to be accommodated by the conventional cs̄ states.”
Herwig++ physics and manual (2008, methodology): “ited Dand Ds mesons were taken from Ref. [49] including recent results for the D′ 1 and D∗ 0 states. The widths of the Ds1 and Ds2 mesons were from the theoretical calculations of Ref. [102] and Ref. [103], respectively. For many of the mesons we were forced to assume that the observed modes saturat”
Properties of Excited Charm and Charm-Strange Mesons (2015, methodology): “This is typical of most such models which are based on some variant of the Coulomb plus linear potential expected from QCD and that often include some relativistic effects [20, 49–55].”
Glueballs, Hybrids, Multiquarks. Experimental facts versus QCD inspired concepts (2007, background): “In agreement with quark model results [175,851], the masses of D∗ s0(2317) and D ∗ s1(2460) are to low to support a straightforward interpretation as cs̄ states; alternative interpretations have therefore been suggested.”
