利用相对论化的双夸克模型哈密顿量,我们计算了以下系统中基态四夸克的质量:,(),,,,和。我们还计算了全重夸克风味组合的宽谱。最后,作为对双夸克模型方法的检验,我们计算了双夸克模型中全重重子的质量。我们的结果可以很快与即将到来的全重三夸克系统的实验数据进行比较。
Using a relativized diquark model Hamiltonian, we calculate the masses ofground-state tetraquarks in the following systems:,(),,,,and. We also compute extensive spectra for the fully-heavy quark flavour combinations. Finally, as a test of the diquark model approach, we compute the masses of fully-heavy baryons in the diquark model. Our results may be compared soon to the forthcoming experimental data for fully-heavy three-quark systems.
