摘要

预测强子谱低能部分的性质是一项具有挑战性的任务，迄今为止，由于量子色动力学(QCD)在低能下的非摄动性质，这项任务仍然是暂定的。在本文中，我们正在探索SO(4)方案的有效性，作为2.5 GeV以下区域类介子态基本QCD结构的代表。我们把注意力集中在计算各种自旋、同位旋和奇偶的介子态的能量和宽度上。

Theoretical results for hadronic masses and their widths in the framework of the SO(4) model

The prediction of properties of the low-energy portion of the hadronic spectrum is a challenging task which, up to day, is still tentatively given due to the nonperturbative nature of quantum chromodynamics (QCD) at low energies. In this paper, we are exploring the validity of the SO(4) scheme, as a representative of the fundamental QCD structure of meson-like states in the region below 2.5 GeV. We have focused our attention on the calculation of the energy and width of meson states of various spin, isospin and parities.
