摘要:

本文提出一种获取四夸克配对哈密顿量精确解的新方法,该方法利用无限维中的代数技术。基于唯象学得到的潜在四夸克候选体,对跃迁阶段涉及的参数进行校准。研究表明,与使用同一形式体系的其他方法相比,转动和振动跃迁理论能更准确地解释重四夸克。为阐明该概念,我们计算了若干四夸克的能谱,即粲、底、底粲以及含开放粲和开放底的系统,并将其与其他粒子的能谱进行对比。

英文摘要:

A novel approach is introduced for obtaining precise solutions of the pairing Hamiltonian for tetraquarks, which utilizes an algebraic technique in infinite dimensions. The parameters involved in the transition phase are calibrated based on potential tetraquark candidates derived from phenomenology. Our investigation shows that the rotation and vibration transitional theory delivers a more accurate explanation for heavy tetraquarks compared to other methods utilizing the same formalism. To illustrate the concept, we compute the spectra of several tetraquarks, namely charm, bottom, bottom-charm and open charm and bottom systems, and contrast them with those of other particles.
