摘要

本文利用Regge现象学研究了\(qq\bar{q}\bar{q}\)、\(ss\bar{s}\bar{s}\)和\(qq\bar{s}\bar{s}\)四夸克的质谱。我们计算了\(qq\bar{s}\bar{s}\)四夸克的基态质量范围,并估计了它们在\((J,M^2)\)平面上的轨迹的Regge参数。利用这些Regge参数,我们计算了\((J,M^2)\)平面中\(qq\bar{q}\bar{q}\)、\(ss\bar{s}\bar{s}\)和\(qq\bar{s}\bar{s}\)四夸克的激发态质量范围。此外,我们还研究了\(qq\bar{q}\bar{q}\)、\(ss\bar{s}\bar{s}\)和\(qq\bar{s}\bar{s}\)四夸克在\((n,M^2)\)平面上的激发径向态的质谱。我们预测了一些新观察到的实验态的潜在量子数,这需要额外的验证,并评估了在不久的将来可能发现的更高的轨道和径向激发态。得到的四夸克的质量关系和质量值对今后的实验研究和这些态的自旋宇称赋值具有重要意义。我们的发现为四夸克的结构和性质提供了有价值的见解,有助于更广泛地理解量子色动力学(QCD)。

Mass spectra of \(qq\bar{q}\bar{q}\), \(ss\bar{s}\bar{s}\) and \(qq\bar{s}\bar{s}\) tetraquarks using Regge phenomenology

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).
