Chiral Symmetry of Heavy-Light Hadrons in Hot/dense Matter

The recent discoveries by the BaBar and CLEO II collaborations on the splitting between D_s and ∼ {D}_s which exhibited surprises in the structure of heavy-light-quark systems are connected - via the Harada-Yamawaki "vector manifestation" of hidden local symmetry - to chiral symmetry restoration expected to take place at some critical temperature T_c in heavy-ion collisions or at some critical density n_c in the deep interior of compact stars, the main theme of this symposium. This unexpected connection exemplifies the diversity of astro-hadronic phenomena discussed in this meeting.
