论文摘要
基于对单人重介子和单一重型重子的String模型方法的研究，我们计算了$ 1S $的质量频谱，以及$ 2S $ - $ 2S $ - Wave，用于魅力和底部介子$（d/d_ {s}，b/b/b/b_ {s}）$。在实验上，已经发现了大多数群众光谱$ 1S $ - 波，而$ 2S $ state的群众部分尚未确定。在本文中，我们将使用单一的轻夸克或diquark模型图像和雷格轨迹模型，并结合扰动处理方法，分析和研究观察到的单一重型介子，进一步预测未观察到的介体质量及其相应的旋转量量子数。
Based on the study of the string model methods of singly heavy mesons and singly heavy baryons, we calculate the mass spectrum of $1S$-and $2S$-wave for both charm and bottom mesons$(D/D_{s}, B/B_{s})$. Experimentally, there are most masses spectra of $1S$-wave have been found, while the masses part of the $2S$-state is not determined. In this paper, we will use singly light quark or diquark model images and Regge trajectory models, combined with perturbation processing methods, to analyze and study the observed singly heavy mesons, further predict the unobserved mesons masses and their corresponding spin-parity quantum numbers.
