Abstract Heavy-light mesons are described in an effective quark theory with a two-body vector-type interaction. The bilocal interaction is taken to be instantaneous in the rest frame of the bound state, but formulated covariantly through the use of a boost vector. The chiral symmetry of the light flavor is broken spontaneously at mean field level. The framework for our discussion of bound states is the effective bilocal meson action obtained by bosonization of the quark theory. Mesons are described by 3-dimensional wave functions satisfying Salpeter equations, which exhibit both Goldstone solutions in the chiral limit and heavy-quark symmetry form Q→∞. We present numerical solutions for pseudoscalarD- andB-mesons. Heavy-light meson spectra and decay constants are seen to be sensitive to the description of chiral symmetry breaking (dynamically generated vs. constant quark mass).
