Summary:We present a comparative study of the pion induced production of \(K^0 \Lambda\) and \(D^- \Lambda_c^+\) off the nucleon. A hybrid framework is utilized by combining an effective Lagrangian method with a Regge approach. We consider the \(t\)-channel process in a plannar diagram by vector-meson Reggeon exchanges and the \(u\)-channel one in a non-planar diagram by baryon Reggeon exchanges. The present model reproduces the \(K^0 \Lambda\) production data well with a few parameters. Having fixed them, we predict the \(D^- \Lambda_c^+\) production, which turns out to be about \(10^4-10^6\) times smaller than the strangeness one, depending on the kinematical regions.
