论文摘要
在有效的现场理论的背景下，我们预测了四个$ 1S $和八个$ 1p $ nonstrange的频谱和八个$ 1p $ nonstrange和奇怪的状态。通过重型夸克有效理论和手性扰动理论的结合，定义了重型膜的大规模形式主义。我们的分析使用质量表达式，这首先涉及全部领先的自我能力校正和引导力量校正重型夸克和手性限制。这些表达式中存在的反对物是使用有关Charmed Meson群众和耦合的可用实验和理论信息拟合的。魅力部门的结果用于对模拟美容媒介谱系的理论期望。观察到的基态的频谱，$ b^{（*）} _ {（s）} $，激动，$ b _ {（s）1} $和$ b^*_ {（s）2} $，美容媒体在我们的理论计算中很好地复制了。激动的标量，$ b^*_ {（s）0} $和axial-vector，$ b^\ prime _ {（s）1} $，尚未发现美容媒介。希望我们的预测可以为进一步的实验探索这些缺失的共鸣提供宝贵的线索。
We predict the spectrum of the four $1S$ and eight $1P$ nonstrange and strange states in the beauty meson family in the context of effective field theory. By the union of heavy quark effective theory and chiral perturbation theory, the mass formalisms for the heavy-light mesons are defined. Our analysis uses mass expressions involving, for the first time, the full leading self-energy corrections and leading power corrections to the heavy quark and chiral limits. The counterterms present in these expressions are fitted using available experimental and theoretical information on the charmed meson masses and couplings. The results from charm sector are used to make theoretical expectations on the analog beauty meson spectrum. The observed spectrum of the ground state, $B^{(*)}_{(s)}$, and excited, $B_{(s)1}$ and $B^*_{(s)2}$, beauty mesons are well reproduced in our theoretical calculations. The excited scalar, $B^*_{(s)0}$, and axial-vector, $B^\prime_{(s)1}$, beauty mesons have not yet been discovered. Hopefully our predictions may provide valuable clues to further experimental exploration of these missing resonances.
