Leading Effects in Hadroproductions of Lambdac and D From Constituent Quark-Diquark Cascade Picture
Abstract
We discuss the hadroproductions of Lambdac, Lambdac bar, D and D bar in the framework of the constituent quark-diquark cascade model taking into account the valence quark annihilation. The spectra of Lambdac and Lambdac bar in pA, Sigma-A and pi-A collisions are well explained by the model using the values of parameters used in hadroproductions of D and D bar. It is shown that the role of valence diquark in the incident baryon is important for D bar productions as well as for Lambdac production.
