Description
Within the framework of non-relativistic QCD, the indirect production of semi-inclusive doubly heavy baryons ($\Xi_{cc}$, $\Xi_{bc}$ and $\Xi_{bb}$) via four main Higgs decay channels and one main top quark decay channel are presented. The contributions from the intermediate diquark states, $\langle bc \rangle [^3 S_1]_{\bar{3}/6}$, $\langle bc \rangle [^1 S_0]_{\bar{3}/6}$, $\langle cc \rangle [^3 S_1]_{\bar{3}}$, $\langle cc \rangle [^1 S_0]_{ 6}$, $\langle bb \rangle [^3 S_1]_{\bar{3}}$, $\langle bb \rangle [^1 S_0]_{6}$, have been taken into consideration. Besides, we also discussed the three main source of the theoretical uncertainties, heavy quark masses, the renormalization scale $\mu_r$, and the nonperturbative transition probability and the corresponding differential distributions. There will be a considerable number of events of $\Xi_{cc}$, $\Xi_{bc}$ and $\Xi_{bb}$ produced per year at the High Luminosity Large Hadron Collider.
