Pion induced Reactions for Charmed Baryons

Abstract

We study pion induced reactions for charmed baryons $B$, $\pi$ + N $\to$ $D^{\ast }$ + $B$. First we estimate charm production rates in comparison with strangeness production using a Regge model which is dominated by vector ($D^{\ast }$ or $K^{\ast }$ ) Reggeon exchange. Then we examine the production rates of various charmed baryons $B$ in a quark-diquark model. We find that the production of excited states are not necessarily suppressed, a sharp contrast to strangeness production, which is a unique feature of the charm production with a large momentum transfer.
