“…In this paper, we shall discuss the production of doubly heavy baryons Ξ QQ ′ through indirectly Higgs boson decays at the HL-LHC and CEPC/ILC. As is well-known, the dominant decay channel of Higgs boson is H 0 → bb and the branching ratio is about 58% [38,39]. For completeness, four main Higgs decay channels, H 0 → bb, cc, Z 0 Z 0 , gg, would be taken into consideration.…”

We systematically analyzed the production of semi-inclusive doubly heavy baryons (Ξ cc , Ξ bc and Ξ bb ) for the process H 0 → Ξ QQ ′ +Q ′ +Q through four main Higgs decay channels within the framework of non-relativistic QCD. The contributions from the intermediate diquark states, cc, 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 0.43×10 4 events of Ξ cc , 6.32×10 4 events of Ξ bc and 0.28×10 4 events of Ξ bb produced per year. There are fewer events produced at the Circular Electron Positron Collider and the International Linear Collider, about 0.26 × 10 2 events of Ξ cc , 3.83 × 10 2 events of Ξ bc and 0.17 × 10 2 events of Ξ bb in operation.

Through the interaction of Higgs with heavy quarks in standard model, we have systematically studied and predicted the production of excited doubly heavy baryons based on non-relativistic QCD theory. The decay widths, differential distributions, and major theoretical uncertainties of the excited doubly heavy baryons via the process $$H \rightarrow \langle QQ'\rangle [n] \rightarrow \Xi _{QQ'}+ \bar{Q'} + \bar{Q}$$ H → ⟨ Q Q ′ ⟩ [ n ] → Ξ Q Q ′ + Q ′ ¯ + Q ¯ are discussed in detail. The spin and color quantum number of the intermediate P-wave diquark state $$\langle QQ'\rangle [n]$$ ⟨ Q Q ′ ⟩ [ n ] can be $$\langle cc\rangle [^{1}P_{1}]_{\varvec{\bar{3}}}$$ ⟨ c c ⟩ [ 1 P 1 ] 3 ¯ , $$\langle cc\rangle [^{3}P_{J}]_{\varvec{6}}$$ ⟨ c c ⟩ [ 3 P J ] 6 , $$\langle bc\rangle [^{1}P_{1}]_{\varvec{\bar{3}}/ \textbf{6}}$$ ⟨ b c ⟩ [ 1 P 1 ] 3 ¯ / 6 , $$\langle bc\rangle [^{3}P_{J}]_{\varvec{\bar{3}}/ \textbf{6}}$$ ⟨ b c ⟩ [ 3 P J ] 3 ¯ / 6 , $$\langle bb \rangle [^{1}P_{1}]_{\varvec{\bar{3}}}$$ ⟨ b b ⟩ [ 1 P 1 ] 3 ¯ and $$\langle bb\rangle [^{3}P_{J}]_{\textbf{6}}$$ ⟨ b b ⟩ [ 3 P J ] 6 , with $$J=0, 1, 2$$ J = 0 , 1 , 2 . The contributions from all summed P-wave states can be about $$3.05\%$$ 3.05 % , $$3.23\%$$ 3.23 % and $$2.19\%$$ 2.19 % of the S-wave states for the production of $$\Xi _{cc}$$ Ξ cc , $$\Xi _{bc}$$ Ξ bc and $$\Xi _{bb}$$ Ξ bb , accordingly. Therefore, there will be about 0.41$$\times 10^4$$ × 10 4 events of $$\Xi _{cc}$$ Ξ cc , 6.35$$\times 10^4$$ × 10 4 events of $$\Xi _{bc}$$ Ξ bc and 0.28$$\times 10^4$$ × 10 4 events of $$\Xi _{bb}$$ Ξ bb produced per year at the HL-LHC, and a smaller number of events would be produced at the CEPC or ILC but with a cleaner background to be measured by the experiments.
