Analysis of the Vector and Axialvector $QQ\bar {Q}\bar {Q}$ Tetraquark States with QCD Sum Rules
/ ZhiGang Wang ; ZunYan Di
In this article, we construct the axialvectordiquarkaxialvectorantidiquark type currents to study both the vector and axialvector $QQ\bar{Q}\bar{Q}$ tetraquark states with the QCD sum rules, and obtain the masses $M_{Y(cc\bar{c}\bar{c},1^{+})} =6.05\pm0.08\,\rm{GeV}$, $M_{Y(cc\bar{c}\bar{c},1^{})} =6.11\pm0.08\,\rm{GeV}$, $M_{Y(bb\bar{b}\bar{b},1^{+})} =18.84\pm0.09\,\rm{GeV}$, $M_{Y(bb\bar{b}\bar{b},1^{})} =18.89\pm0.09\,\rm{GeV}$.
