| Abstract: | We construct the axialvector and tensor current operators to systematically investigate the ground and first radially excited tetraquark states with quantum numbers J~(PC)= 1~(+-)using the QCD sum rules. We observe one axialvector tetraquark candidate for Z_c(3900) and Z_c(4430), two axialvector tetraquark candidates for the Z_c(4020), and three axialvector tetraquark candidates for Z_c(4600). |
