摘要
Recent signals for narrow hadrons containing heavy and light flavors are compared with quark model predictions for spectroscopy, strong decays, and radiative transitions. In particular, the production and identification of excited charmed and c (s) over bar states are examined with emphasis on elucidating the nature of 0(+) and 1(+) states. Roughly 200 strong decay amplitudes of D and D-s states up to 3.3 GeV are presented. Applications include determining flavor content in eta mesons and the mixing angle in P and D wave states and probes of putative molecular states. We advocate searching for radially excited D-s(*) states in B decays.
