AbstractWe investigate the possibility to study the charmoniumlike state Z(c)(3900) through the pion-induced production off a nuclear target. By using a high-energy pion beam, the Z(c)(3900) can be produced off a proton or nucleus though the Primakoff effect. The production amplitude is calculated in an effective Lagrangian approach combined with the vector dominance model. The total cross sections of the p(pi(-), Z(c)(-)(3900) and p(pi(-), Z(c)(-)(3900) -> J/psi pi(-)) reactions are calculated, and their order of magnitude is about 0.1 and 0.01 nb, respectively, with an assumption of branch ratio 10% for the Z(c)(3900) decay in J/psi pi channel. If the proton target is replaced by a nuclear target, the production of the Z(c)(3900) enhances obviously. The predicted total cross sections for the A(pi(-), Z(c)(-)(3900) and A(pi(-), Z(c)(-)(3900) -> J/psi pi(-)) reactions with A = C-12 or Pb-208 are on the order of magnitude of 100 and 10 nb, respectively, which is about one thousand times larger than the cross sections off a proton target. Based on these results, we suggest the experimental study of the Z(c)(3900) by using high-energy pion beams with a nuclear target at facilities such as COMPASS and J-PARC.
