Could Zc(3900) be a IGJP=1+1+ D*(D) over bar molecular state?

We investigate the nature of the recently observed narrow resonance Z(c)(3900), which is assumed to be a D*(D) overbar molecular state with quantum numbers I(G)J(P) = 1(+)1(+). Using QCD sum rules, we consider contributions up to dimension 8 in the operator product expansion and work at the leading order in alpha(s). The mass we arrived at is (3.88 +/- 0.17) GeV, which coincides with the mass of Z(c)(3900).
