Abstract We study the effect of a hidden charm nuclear excited state N-c (c) over bar* in the pi(-)p -> D-Sigma(+)(c) reaction near threshold using an effective Lagrangian approach. We calculate the background contribution of the t and u channels by the D*(0) vector meson exchange and Sigma(++)(c) intermediate state, respectively. We show that the consideration of a N-c (c) over bar* resonance provides an enhancement of the total cross section close to the reaction threshold. We also evaluate the differential cross section for different energies and we study the angle dependence. It is expected that our model calculations will be tested in future experiments.
