Summary
In the Parton Fusion Model (PFM) the intrinsic charm (IC) mechanism can induce a significant contribution to the differential cross-sections of charmed hadrons at large Feynman-x in pp collisions. The possibility to include the intrinsic charm component in the Quark-Gluon String Model (QGSM) is also presented and the results from the two models are compared with each other and with existing experimental data on D,\(\bar D\) and Λc hadroproduction. In connection with HERA experiments, the effects of intrinsic charm as predicted by PFM in high-energy photoproduction are carefully investigated.
