Abstract

We investigate the hadronic production of the doubly heavy baryon \$\Xi\_bc\$ at the large hadron collider (LHC), where the contributions from the four \$(bc)\$-diquark states \$(bc)\_\bf3,6^1S\_0\$ and \$(bc)\_\bf3,6^3S\_1\$ have been taken into consideration. Numerical results show that sizable \$\Xi\_bc\$ events about \$ 1.110^7\$ and \$2.0\times10^9\$ per year can be produced for the case of the center-of-mass energy \$S=7\$ TeV and \$S=14\$ TeV accordingly. For experimental usage, the total and the interested differential cross-sections are estimated under some typical \$p\_T\$- and \$y\$- cuts for the LHC detectors CMS, ATLAS and LHCb, respectively.
