Hadronic production of ${\Xi }_{bc}$ with the intrinsic heavy-quark content at a fixed-target experiment at the LHC

Abstract

In this paper, we make a detailed study on the hadronic production of the ${\Xi }_{bc}$ baryon at a fixed target experiment at the LHC (After@LHC). In estimating the production cross sections, the $(g+g)$, $(g+c)$ and $(g+b)$ 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 $(g+c)$ and $(g+b)$ production mechanisms give sizable contributions to the ${\Xi }_{bc}$ production, and the $(g+b)$ mechanism dominates the production. The results show that there are about $3.40\times 10^5$ ${\Xi }_{bc}$ events can be produced per year at After@LHC if the integrated luminosity of After@LHC can be up to $2{\mathrm{fb}}^{-1}$ per year. Moreover, the intrinsic heavy quarks can have significant impact on the production, which inversely makes the intrinsic component be possibly tested at the After@LHC.
