Remarks on the $S$-wave masses of singly heavy mesons

Jisi Pan, Ji-Hai Pan

AI总结:

本研究结合弦模型、单轻夸克或双夸克图像、Regge轨迹及微扰方法,计算并预测粲、底单重介子的$1S$与$2S$波质量及自旋-宇称量子数。

摘要:

基于对单重介子和单重重子的弦模型方法的研究,我们计算了粲介子和底介子($D/D_s$、$B/B_s$)的$1S$波和$2S$波质量谱。实验上,大多数$1S$波质量谱已被发现,而部分$2S$态的质量尚未确定。本文将利用单轻夸克或双夸克模型图像以及Regge轨迹模型,并结合微扰处理方法,分析和研究已观测到的单重介子,进一步预测尚未观测到的介子质量及其相应的自旋-宇称量子数。

英文摘要:

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.
