Properties of orbitally excited heavy-light (Qq¯) mesons

Orbitally excited heavy-light (Qq¯) mesons are potentially important as tools for tagging the flavors and momenta of ground-state pseudoscalars detected through weak decays. We use heavy-quark symmetry supplemented by insights gleaned from potential models to estimate masses and widths of p-wave B, ${\mathit{B}}_{\mathit{s}}$, and ${\mathit{D}}_{\mathit{s}}$ mesons. We generalize these results to higher excitations.
