Strong decays of molecular states Zc+ and Zc′+

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