英文摘要	The effects of the intrinsic charm on the hadronic production of Xi(cc) are studied. By taking reasonable intrinsic charm component into account, the change of the theoretical prediction on the production of Xi(cc) for LHC and Tevatron is small, but in contrast it may enhance significantly for SELEX. The reason is that the collision energy at LHC and Tevatron is so large that the gluon-gluon fusion sub-process, which is irrelevant to intrinsic charm, becomes dominant. But the situation for SELEX is quite different. Our numerical results for SELEX show that by considering all the contributions from various sub-processes, the predicted cross section may be enhanced by a factor so big as 10(2) due to a modulating intrinsic charm being taken into account. Therefore, the hadronic production of Xi(cc) at SELEX may be sensitive enough in observing the intrinsic charm inside the incident hadrons.
