轨道激发的重-轻介子（[ital Q[bar Q]]）作为标记通过弱衰变检测到的基态伪标量的味道和动量的工具，具有潜在的重要意义。我们使用重夸克对称，辅以从势能模型中收集的见解来估计[数字p]波[数字B]，[数字B][次[数字s]]和[数字D][次[数字s]]介子的质量和宽度。我们把这些结果推广到更高的激励。
Orbitally excited heavy-light ([ital Q[bar q]]) 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 [ital p]-wave [ital B], [ital B][sub [ital s]], and [ital D][sub [ital s]] mesons. We generalize these results to higher excitations.
