Abstract
Abstract We construct the axialvector and tensor current operators to systematically investigate the ground and first radially excited tetraquark states with quantum numbers using the QCD sum rules. We observe one axialvector tetraquark candidate for and , two axialvector tetraquark candidates for the , and three axialvector tetraquark candidates for .
