摘要

在这项研究中，我们选择了在二夸克和反二夸克对之间有明确P波的二夸克-反二夸克型四夸克电流，来研究量子数为.的隐粲四夸克态的基态和第一次径向激发。我们还获得了四夸克的最低矢量质量，并对现有态进行了可能的赋值。确实存在一个能量约为 4.75 GeV 的隐粲四夸克态，它是 BESIII 数据的第一个径向激发态。

Ground states and first radial excitations of vector tetraquark states with explicit P-waves via QCD sum rules* * Supported by the National Natural Science Foundation of China (12175068)

In this study, we chose the diquark-antidiquark type four-quark currents with an explicit P-wave between the diquark and antidiquark pairs to study the ground states and first radial excitations of the hidden-charm tetraquark states with quantum numbers

. We also obtained the lowest vector tetraquark masses and made possible assignments of the existing

states. There indeed exists a hidden-charm tetraquark state with

at an energy of approximately 4.75 GeV as the first radial excitation that accounts for the BESIII data.
