Excited heavy mesons

Open publisher page 17 citations

Abstract

We discuss an effective action for heavy excited mesons interacting with light pseudoscalars and vector mesons that combines both chiral and heavy-quark symmetry. We estimate the axial-vector couplings, masses, and mixed axial-vector couplings of the excited mesons to order one in the heavy-quark mass. The general issue of reparametrization invariance in heavy-quark effective theories is also discussed.
