Production of doubly heavy baryons via Higgs boson decays

Abstract

We systematically analyzed the production of semi-inclusive doubly heavy baryons (${\Xi }_{cc}$, ${\Xi }_{bc}$ and ${\Xi }_{bb}$) for the process $H^0\to {\Xi }_{Q{Q}^{\prime }}+\overline{Q^{\prime }}+\bar{Q}$ through four main Higgs decay channels within the framework of non-relativistic QCD. The contributions from the intermediate diquark states, $⟨cc⟩{[}^1{S}_0{]}_6$, $⟨cc⟩{[}^3{S}_1{]}_{\bar{3}}$, $⟨bc⟩{[}^3{S}_1{]}_{\bar{3}/6}$, $⟨bc⟩{[}^1{S}_0{]}_{\bar{3}/6}$, $⟨bb⟩{[}^1{S}_0{]}_6$ and $⟨bb⟩{[}^3{S}_1{]}_{\bar{3}}$, have been taken into consideration. The differential distributions and three main sources of the theoretical uncertainties have been discussed. At the High Luminosity Large Hadron Collider, there will be about 0.43$\times 10^4$ events of ${\Xi }_{cc}$, 6.32$\times 10^4$ events of ${\Xi }_{bc}$ and 0.28$\times 10^4$ events of ${\Xi }_{bb}$ produced per year. There are fewer events produced at the Circular Electron Positron Collider and the International Linear Collider, about $0.26\times 10^2$ events of ${\Xi }_{cc}$, $3.83\times 10^2$ events of ${\Xi }_{bc}$ and $0.17\times 10^2$ events of ${\Xi }_{bb}$ in operation.
