摘要In this article, we assume that there exist hidden charmed tetraquark states with spin-parity J (P)=1(-), and we calculate their masses with the QCD sum rules. The numerical result indicates that the masses of the vector hidden charmed tetraquark states are about M (Z) =(5.12 +/- 0.15) GeV or M (Z) =(5.16 +/- 0.16) GeV, which are inconsistent with the experimental data on the pi (+) chi (c1) invariant-mass distribution. The hidden charmed mesons Z (1), Z (2) or Z may be scalar hidden charmed tetraquark states, hadro-charmonium resonances or molecular states.
