Abstract

In this talk, we report the study of $\pi^- p \to K^{*0} \Lambda$ and $\pi^- p \to D^{*-} \Lambda_c^+$ reactions by using an effective Lagrangian method and a hybrid Regge model. The total and differential cross sections for the $K^{*0} \Lambda$ production are first calculated and then those for the $D^{*-} \Lambda_c^+$ one are estimated. The two models yield different results, each exhibiting specific features. Our prediction for the charm production provides valuable information about the upcoming J-PARC experiment.
