摘要：

In this paper, we make a detailed study on the hadronic production of the Ebc baryon at a fixed-target experiment at the LHC (AFTER@LHC). In estimating the production cross sections, the (g thorn g), (g thorn c), and (g thorn b) production mechanisms are considered. For the initial heavy quarks, in addition to the extrinsic component, we also consider the intrinsic component. It is found that the (g thorn c) and (g thorn b) production mechanisms give sizable contributions to the Ebc production, and the (g thorn b) mechanism dominates the production. The results show that there are about 3.40 x 105 Ebc events that can be produced per year at the AFTER@LHC if the integrated luminosity of the AFTER@LHC can be up to 2 fb-1 per year. Moreover, the intrinsic heavy quarks can have a significant impact on production, which inversely makes the intrinsic component be possibly tested at the AFTER@LHC.
