摘要

We study pion-induced binary reactions for charmed baryons, pi + N -%26gt; D* + B, where B is a charmed baryon of ground or excited state. First we estimate charm production rates in comparison with strangeness production using a Regge model, which is dominated by vector (D* or K*) 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 is not necessarily suppressed, a sharp contrast to strangeness production, which is a unique feature of the charm production with a large momentum transfer.
