/\_c+ - /\_c- production asymmetries in two component models

Abstract

Experiments on charm hadroproduction have shown a substantial difference in the production of charm and anticharm hadrons. In this work we study /\_c+ and /\_c- inclusive production in p-N interactions in the framework of two component models. We show that the recombination two component model gives a qualitatively and quantitatively good description of /\_c production while the intrinsic charm model seems to be ruled out by recent experimental data from the SELEX Collaboration.
