Abstract:	In earlier publications we have analyzed the strong and radiative decays of heavy hadrons in a formalism which incorporates both heavy-quark and chiral symmetries. In particular, we have derived a heavy-hadron chiral Lagrangian whose coupling constants are related by the heavy-quark flavor-spin symmetry arising from the QCD Lagrangian with infinitely massive quarks. In this paper, we reexamine the structure of the above chiral Lagrangian by including the effects of 1/m(Q) corrections in the heavy-quark effective theory. The relations among the coupling constants, originally derived in the heavy-quark limit, are modified by heavy-quark symmetry-breaking interactions in QCD. Some of the implications are discussed.
