Viable semi-relativistic quark model of heavy-light systems

Abstract
The semi-relativistic quark potential model is surprisingly powerful for heavy-light systems if the bound state equation is treated correctly using 1/m_Q expansion with heavy quark mass m_Q. We elucidate the reasons why our semi-relativistic model succeeds in predicting and reproducing all the mass spectra of heavy-light systems so far reported, D/D_s/B/B_s, by reviewing and comparing recent experimental data with the results of our model and others. Especially the mass spectra of the so-called D_{sJ}, i.e., D_{s0}^* and D_{s1}', are successfully reproduced only by our model but not by other models.
