论文摘要
在本文中，我们研究了包含两个重夸克的重子的质谱。魅力链（$ cc $）和底部链式（$ bc $），带有轻夸克（$ u，d，s $）。在线性恢复轨迹的假设下，我们得出了斜率比，截距和重子质量之间的关系。使用这些关系，获得了$ξ_{cc} $，$ξ_{bc} $，$ω__{cc} $的基态质量，并获得了$ω__{bc} $ baryons。提取了这些重子的斜坡和regge截距的值，以估计（$ j，m^{2} $）和（$ n，m^{2} $）飞机中的激发状态质量。将我们获得的结果与可用的和其他理论预测的实验观察结果进行了比较，这可能是对实验未知的重型baryon光谱的解释的宝贵补充。
In this article, we study the mass spectra of baryons containing two heavy quarks; charm-charm ($cc$) and bottom-charm ($bc$) with a light quark ($u,d,s$) within the framework of Regge phenomenology. With the assumption of linear Regge trajectories we have derived the relations between slope ratios, intercepts, and baryon masses. Using these relations, the ground state masses of $Ξ_{cc}$, $Ξ_{bc}$, $Ω_{cc}$, and $Ω_{bc}$ baryons are obtained. The values of Regge slopes and Regge intercepts are extracted for these baryons to estimate the excited state masses in both the ($J,M^{2}$) and ($n,M^{2}$) planes. Our obtained results are compared with the experimental observations where available and other theoretical predictions, which could be a valuable addition to the interpretations of experimentally unknown heavy baryon spectra.
