Abstract
The two newly observed hidden-charm mesons Zc(+)[3900] and a possible partner state Zc'(+)[3950] with quantum numbers J(P) = 1(+) are considered as hadronic molecules composed of bar(D)D* and bar(D)* D*, respectively. We give predictions for the decay widths of the strong two-body transitions Zc(+) -> H + pi(+) and Zc' -> H + pi(+) with H = Psi(nS), hc(mP) in a phenomenological Lagrangian approach.
