Excited charmed mesons in chiral perturbation theory

Abstract Heavy meson, p- to s-wave, one-pion transitions are studied in the context of the union of heavy quark and chiral symmetries. The interactions are described by an effective lagrangian density invariant under the combined heavy quark and chiral symmetries. We study the pattern of the heavy quark symmetry breaking by considering 1 m Q corrections to the infinite mass limit.
