A study of reactions for kaon production in heavy ion collisions.

Parametrizations of total cross sections sufficient for all channels of the $\pi B \rightarrow Y K$ reactions are completed using a resonance model. As well as discussing the $\pi N \rightarrow \Lambda K$ reactions, which were not presented in our previous publications, we present the differential cross section for $\pi N \rightarrow \Lambda K$. This report also aims at presenting supplementary discussions to our previous work.
