摘要:

本文采用Regge唯象学探究$qq\ar{q}\ar{q}$、$ss\ar{s}\ar{s}$和$qq\ar{s}\ar{s}$三类四夸克的质谱。我们计算了$qq\ar{s}\ar{s}$四夸克的基态质量范围,并估算了其在$(J,M^2)$平面上雷唯轨迹的相关参数。利用这些参数,我们算出了三类四夸克在$(J,M^2)$平面内的激发态质量范围。此外,我们还研究了三类四夸克在$(n,M^2)$平面上的径向激发态质谱。我们预测了部分新观测到的实验态的可能量子数(这些态仍需进一步验证),并评估了近期或可被探测到的更高轨道与径向激发态。所得的四夸克质量关系与质量值可为未来实验搜寻及这些态的自旋-宇称指认提供参考。我们的研究结果为理解四夸克的结构与性质提供了宝贵洞见,有助于深化对量子色动力学(QCD)的整体认知。

英文摘要:

In this paper, we explore the mass spectra of $qq\bar{q}\bar{q}$, $ss\bar{s}\bar{s}$ and $qq\bar{s}\bar{s}$ tetraquarks by employing Regge phenomenology. We calculate the range for ground state masses of $qq\bar{s}\bar{s}$ tetraquarks, and estimate the Regge parameters for their trajectories in $(J,M^2)$ plane. Using these Regge parameters we have calculated range for the excited state masses of $qq\bar{q}\bar{q}$, $ss\bar{s}\bar{s}$ and $qq\bar{s}\bar{s}$ tetraquarks in $(J,M^2)$ plane. Also, we have investigated the mass spectra of $qq\bar{q}\bar{q}$, $ss\bar{s}\bar{s}$ and $qq\bar{s}\bar{s}$ tetraquarks for their excited radial states in $(n,M^2)$ plane. We predict the potential quantum numbers of some newly observed experimental states, which necessitate additional validation, and assess the higher orbital and radial excited states that may be identified in the near future. The obtained mass relations and mass values of tetraquarks can be useful in future experimental searches and the spin-parity assignment of these states. Our findings provide valuable insights into the structure and properties of tetraquarks, contributing to the broader understanding of Quantum Chromodynamics (QCD).
