Production of strange and charmed baryons in pion induced reactions

Abstract

We study the strangeness and charm productions induced by the pion beam, i.e. the ${\pi }^{-}$p $\to$ $K^{\ast 0}\Lambda$ and ${\pi }^{-}$p $\to$ $D^{\ast -}{\Lambda }_c^{+}$ reactions, based on two different theoretical frameworks: an effective Lagrangian method and a Regge approach. In order to estimate the magnitude of the charm production relative to that of the strangeness production, we assume that the coupling constants for the charmed meson and baryon vertices are the same as those for the strangeness channel. We found that the total cross section for the charm production was about $10^3-10^6$ times smaller than that for the strangeness production, depending on theoretical approaches and kinematical regions. We also discuss each contribution to observables for both reactions. In general, the Regge approach explains the experimental data very well over the whole energy region.
