论文摘要
我们使用称为基础轻较量化的多体基函数方法以汉密尔顿动力学的前形式研究全链的四夸克人。哈密顿模型包含横向和纵向限制电势以及一个单格换交易的有效潜力。我们计算了集中在最低状态的两阶段两座状态的质量。我们还计算了梅森 - 梅森分手阈值的两夸克和四夸克估计。结果表明，最低的两链二 - 安提卡姆状态不是紧密结合的四夸克。我们讨论了簇分解原理对在光线上配制的理论的含义，并介绍了对相同颗粒的处理以及对量子状态空间的色彩限制。
We study all-charm tetraquarks in the front form of Hamiltonian dynamics using the many-body basis function approach known as basis light-front quantization. The model Hamiltonian contains transverse and longitudinal confining potentials and a one-gluon-exchange effective potential. We calculate masses of two-charm-two-anticharm states focusing on the lowest state. We also calculate two-quark and four-quark estimates of meson-meson breakup threshold. The results suggest that the lowest two-charm-two-anticharm state is not a tightly bound tetraquark. We discuss implications of the cluster decomposition principle for theories formulated on the light front and present our treatment of identical particles together with color-singlet restrictions on the space of quantum states.
