- Abstract: In this work we study the D∗D¯∗ current with QCD sum rules. We write the correlation function using the general current corresponding to the D∗D¯∗ system and then use spin projectors to obtain the correlation function in the 0+, 1 + and 2+ spin-parity configurations. The purpose of the present work is to investigate the possibility of explaining the recently reported Zc(4025) as a D∗D¯∗ moleculelike state. As a result we find a state for each spin case with a very similar mass: MS=0 = (3943 ± 104) MeV, MS=1 = (3950 ± 105) MeV, MS=2 = (3946 ± 104) MeV. We discuss that our mass results, within error bars, for 1+ or 2+ are both compatible with Zc(4025). However, our results are also compatible with a possible D∗D¯∗ bound state, in agreement with predictions of some previous works. We have also calculated the current-state coupling which turns out to be larger in the 2+ case.
