چکیده
Leading charm hadrons produced in hadron-nucleus interactions cannot be adequately described within the parton fusion model. Recent results on charm baryon production in Σ − A interactions at 330 GeV with the WA89 detector disagree with fusion predictions. Intrinsic heavy quark pairs in the Σ − (dds) wavefunction provide a simple mechanism for producing fast charm hadrons. We calculate leading charm baryon production from Σ − , π − and p projectiles in a two component model combining parton fusion with intrinsic charm. Final state D − , Σ

Leading charm in hadron-nucleus interactions in the intrinsic charm model
Leading charm hadrons produced in hadron-nucleus interactions cannot be adequately described within the parton fusion model. Recent results on charm baryon production in X A interactions at 330 GeV with the WA89 detector disagree with fusion predictions. Intrinsic heavy quark pairs in the Z (dds) wavefunction provide a simple mechanism for producing fast charm hadrons. We calculate leading char...
متن کاملΛ + c − Λ − c production asymmetries in two component models
Experiments on charm hadroproduction have shown a substantial difference in the production of charm and anticharm hadrons. In this work we study Λ+ c and Λ 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 Λ c production while the intrinsic charm mod...
متن کاملOn the intrinsic charm and the recombination mechanisms in charm hadron production
We study Λc production in pN and π −N interactions. Recent experimental data from the SELEX and E791 Collaborations at FNAL provide important information on the production mechanism of charm hadrons. In particular, the production of the Λc baryon provides a good test of the intrinsic charm and the recombination mechanisms, which have been proposed to explain the so called leading particle effec...
متن کاملSignals for Intrinsic Charm in High Energy Interactions
The prospects to test the hypothesis of intrinsic charm quarks in the proton are investigated. We consider how this component can be directly or indirectly probed in deep inelastic scattering at HERA and in fixed target experiments and find that an overlooked signal might be present in existing NMC data. Applying the intrinsic charm model to hadron collisions we compare the resulting charm prod...
متن کاملOn the Intrinsic Charm Component of the Nucleon
Using a D meson cloud model we calculate the squared charm radius of the nucleon . The ratio between this squared radius and the ordinary baryon squared radius is identified with the probability of “seeing” the intrinsic charm component of the nucleon. Our estimate is compatible with those used to successfully describe the charm production phenomenology. In the early eighties there was a hope t...
