A QCD field collerator based model will be discussed, which exhibits
confinement and chiral symmetry. The effective Lagrangian is of a NJL
type with confinement built in. Constituent masses are dynamically
obtained from the string tension and are state dependent. Properties
of the mass spectrum will be presented. The effective Lagrangian is
applied to study the heavy-light quark system. Effects of coupled
channels on the recently discovered narrow DS*(2317) and DS*(2632)
mesons are studied to see whether one can accomodate these mesons as
radially excited states of a c and s_bar quark.
