Excited heavy-light systems and hadronic transitions - art. no. 114004

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 (pi ,K....) hadronic transitions among h eavy-light excited and ground states. To calculate the excited states masse s and wave functions, we must resort to a relativistic quark model. Our mod el includes the leading order corrections in 1/m((c,b)) (e.g., mixing). Num erical results for masses and light hadronic transition rates are compared to existing experimental data. The effective Coupling of the chiral quark m odel can be determined by comparing with independent results from lattice s imulations (g(A)(8) =0.53 +/- 0.11) or fitting to known widths (g(A)(8) = 0 .82 +/- 0.09).
