本文构造了轴矢量和张量流算符,利用QCD求和规则系统地研究了基态四夸克态和第一径向激发四夸克态的量子数,观察到对于的有一个轴矢量四夸克候选,对于的有两个轴矢量四夸克候选,对于的有三个轴矢量四夸克候选。
In this paper, we construct the axialvector and tensor current operators to investigate the ground state tetraquark states and the first radially excited tetraquark states with the quantum numbersvia the QCD sum rules systematically, and observe that there are one axialvector tetraquark candidate for theand, two axialvector tetraquark candidates for the, three axialvector tetraquark candidates for the.
