论文摘要
由重型重子研究的实验进步的激励，我们研究了$λ$模板中奇怪的单个重型重子的质谱，其中采用了相对论夸克模型和无限移动的高斯基础函数方法。结果表明，实验数据可以由预测的质量很好地再现。详细分析了波函数的均方根半径和径向概率密度分布。同时，质谱使我们能够在$（j，m^{2}）$ plane中成功构建regge轨迹。我们还初步向最近观察到的重子分配了量子数，包括$ξ_{c}（3055）$，$ξ_{c}（3080）$，$ξ_{c}（2930）$，$ξ_{c} $蒜{最后，显示了奇怪的单个重型重子的光谱结构。因此，我们预测了几个在即将进行的实验中可能会观察到的几个新重子。
Motivated by the experimental progress in the study of heavy baryons, we investigate the mass spectra of strange single heavy baryons in the $λ$-mode, where the relativistic quark model and the infinitesimally shifted Gaussian basis function method are employed. It is shown that the experimental data can be well reproduced by the predicted masses. The root mean square radii and radial probability density distributions of the wave functions are analyzed in detail. Meanwhile, the mass spectra allow us to successfully construct the Regge trajectories in the $(J,M^{2})$ plane. We also preliminarily assign quantum numbers to the recently observed baryons, including $Ξ_{c}(3055)$, $Ξ_{c}(3080)$, $Ξ_{c}(2930)$, $Ξ_{c}(2923)$, $Ξ_{c}(2939)$, $Ξ_{c}(2965)$, $Ξ_{c}(2970)$, $Ξ_{c}(3123)$, $Ξ_{b}(6100)$, $Ξ_{b}(6227)$, $Ξ_{b}(6327)$ and $Ξ_{b}(6333)$. At last, the spectral structure of the strange single heavy baryons is shown. Accordingly, we predict several new baryons that might be observed in forthcoming experiments.
