摘要

In the present paper, we present detailed discussions on the hadronic production of Ξ c c at a fixed target experiment at the LHC (After@LHC). The charm quarks in the hadron could be either extrinsic or intrinsic. By using the Brodsky-Hoye-Peterson-Sakai (BHPS) model as the intrinsic charm distribution function in the proton, we observe that even if by setting the proportion of finding the intrinsic charm in a proton as A in = 1 % , the total cross sections for the g + c and c + c production mechanisms shall be enhanced by nearly two times. Thus, the number of Ξ c c events to be generated at the After@LHC can be greatly enhanced. Since the total cross sections and differential distributions for the Ξ c c production at the After@LHC are sensitive to the value of A in , the After@LHC could be a good platform for testing the idea of intrinsic charm.
